Not to worry. I am also using an "interlaced" display, and since I bought mine over a year-and-a-half ago, I don't think I am going to upgrade my set anytime soon either (although, I am looking at a RP HDTV right now...... and then if I end up getting one, then that set is going to go in my living room...... my current 27-inch interlaced set is in my bedroom, which is where my home theater is). But still, there are some high quality DVD Players that are still available out there, even though, they may be found on the used market right now. The "high-end non-progressive" players that might be of interest to you may include models such as the Pioneer Elite DV-09, the Sony DVP-S7000, and the later version of that model, the Sony DVP-S7700. And while those may be available anywhere from the mid $300's to about the low $800's (depending on which model you choose), I still think that it is worth looking at a progressive scan model anyway, even if you don't intend to use the progressive scan capability of that player right now. But it would be good to have just in case, in any event, that you may end up upgrading to a HDTV sometime in the next few years. If you do that, you're going to come out WAY ahead of the game that way. Because when you finally get your HDTV, you'll already have a player that can take advantage of the high definition technology and picture quality that your new HDTV will offer at that time. All you have to do is either change connections, or hit a switch, and you are there. I personally have a Pioneer Elite DV-37. And my DV-37 is a progressive scan player. But during the first seven months of ownership, it was used with my interlaced Panasonic 27-inch television (first with the S-Video connection from the output of the Pioneer Elite DV-37 to the input of the Panasonic CT-27SF37, then later on, with the component video connection from again, the outputs of the Pioneer Elite DV-37 to the component video inputs of the Pansonic telly (with improved picture quality mind you)). That was because in addition to the connections that I have previously explained to you, the Pioneer Elite DV-37 also has an "interlaced/auto/progressive" switch on its rear panel, and all I had to do is make the connection(s) previously explained, and move the switch to the "interlaced" position, and I was all and done with. I suspect that my Pioneer Elite DV-37 will look even better when it displays a progressive signal, but since I don't have a HDTV to take advantage of that capability right now, I will never find out how good a picture the DV-37 will display until I get such a display. But I do know that using the component video connections with the interlaced setting on the player (with both the player and the TV throughly calibrated after setup), my Panasonic has displayed an excellent picture. The picture quality on my TV has never looked better. I know my newly acquired Toshiba SD-2700 pales by comparison. That alone is saying a whole lot.
But now, if you want to take a look at all three of the players that I just listed, then that's fine and dandy and all. But I think that you should still look at a progressive scan player right now anyway. If for nothing else, it will make upgrading a hell of lot easier later on down the road. And besides, progressive scan players are affordable enough right now, that it would be pointless not to be without one. And just like I said, they can be used with interlaced displays. All you have to do is reset the switch on the back of the player.
While I may not exactly advise you to get a Pioneer Elite DV-37 (though it may not be a bad idea), unless of course you want to, there are other players that are available, that are just as good in picture quality as the Pioneer Elite DV-37, but are more affordable, and can be used with interlaced displays as well. And those players are:
(01). Toshiba SD-3750 ($200.00).
(02). Toshiba SD-4700 ($250.00).
(03). Toshiba SD-5700 ($350.00).
(04). Panasonic RP-56 ($220.00).
(05). Philips Q50 ($500.00)*.
* means that I understand that this is a hot player right now. It has a Faroudja digital signal processor (which results in its razor sharp picture. I saw one at Circuit City two weekends ago) and audiophile grade "op amps", and I suspect, a decent transport (but no display on the front panel..... which is fine and dandy..... both my Pioneer Elite DV-37 and Toshiba SD-2700 have front panel displays, and in both cases, I switch them off when I am watching movies....... I think front panel displays are nothing but a distraction anyway...... so with the Philips not having one altogether, the less circuitry to f**k with the picture and the sound, the better. That would be one less thing to turn off when I am watching movies)). You may be urged to check out this player as well.
Let us know what you decide on later on.
Happy Holidays to you.
