Look on ebay. CRT technology is more established and being replace by the new technologies. However, it is still the best format with the best picture for hometheater. Because it has been around so long you can get good used one. But make sure you check to see how many hours the bulbs have on them. The bulbs can be expensive. Go on ebay and check for used projectors. Another disadvantage is you will need a tech to calibrate the projector as it is beyond the capabilities of even astude hometheater buff. If you go with Digital Light processing, you can set the projector up yourself hence there popularity. But remember this is new technology and as always "new" comes with a premium price. I have seen Crt projectors go for as little as 1500.00 on ebay but dlp usually cost a few thousand at the minimum. If money is the determining factor, buy the used crt projector and pay a tech to set it up. You will need a very very dark room for crt as light control is much more critical which is a second reason why dlp is becoming more popular. A third alternative is an LCD projector. In general the picture will be similar to dlp and the cost about the same. Sony makes some very good ones but expect to pay at least 5 grand even on a good internet deal. I think there are some older LCD that do not cost as much.
