which turntable to buy for $1500 best value ?


i have a rega p2 hooked up to an arcam fmj a18. i want to take a considerable jump with my tt. i am considering marantz 15s1 but wonder with the great cartridge it comes with, is that what i am basicly paying for or does the table belong in that price range. other possibilities are the concept, used p5, used scout [heard they were tricky to set up] or possibly a rp6 which would break me for a while.

When pitch wavers, trailing edges of piano notes seem to blur. That is quite noticeable, probably more noticeable to me than absolute pitch. The Notts Hyperspace which eventually supplanted the Sota Star Sapphire III in my system, definitely was free of that problem. But you make a good point; my SSSIII was early 90s vintage, and from what I gather the "Star" model is still made. The early and late versions might be the same in name only. Also, yes, the issue may stem from mounting the motor to the plinth where the platter and bearing ride in the spring suspension. Thus the belt has to stretch and relax in tune with the suspension, unless the environment is dead quiet and totally free of mechanical feedback.
wow, all this info has been very helpful, thanks to all. it seems like everyday i find my self looking at tt's i have not considered the day before. now, i am really considering the rega rp3 with elise for 650 and a hall mmf 7 for 550. they both seem like great deals, way cheaper then my spending limit which i would use the rest for a good cart or a DIY bootlehead seduction. both tt's i have a feeling will blow my p2 out of the water. and in a few years i will probably upgrade to one of the great tables that you guys have taught me about. if you had to choose one of the 2, which one would you go with? thanks again
The Clearaudio Concept is a great TT that should just fit your budget, especially if you can stretch a bit further for the version that includes an MC cartridge. I think that package is $2,000 new.
There was a post about the Concept on audiokarma about a month ago. Here's what I said there:

My opinion: I would advise you not to buy a Concept. After many months as a staunch defender of Clearaudio, I have now had sufficient quality control problems that I wouldn't recommend their products at all.

The short version is:

(1) June: Bought a Concept. Loved the sound, loved the looks.
(2) August: the stylus fell out of the cartridge while playing a record. Sent it to Clearaudio, they refused to cover it under the warranty. Spent another $200 on a new Concept MM cartridge.
(3) September: the locking screw for the tonearm's VTA adjustment fell out. Had to have Clearaudio send me a new screw.
(4) December: having fallen in love with vinyl and having found a good deal on an Innovation, upgraded to the Innovation. Within 2 days, it became apparent that the motor and/or bearing were defective.
(5) December: the power supply broke on the Concept. The male plug in the back of the turntable that the power supply plugs into broke off inside the plug.
(6) January: returned the Concept to the dealer for a refund in light of all the problems. Just bought a VPI Classic. Maybe it'll have reliability issues down the line, maybe not. But they couldnt be worse than the problems I've had with Clearaudio.

In sum, Clearaudio products have amazing sound and looks -- WHEN they work. For myself, i'd never buy another of their products in my life.
wanted to thank everyone for their advice and knowledge, after extensive reading and the direction from this thread, i decided to save a few more dollars and get a new well tempered simplex. i do wish it had more of a look to it but the music is really all that matters. the down side is having to wait a couple more months before i can buy a wothy cartridge.
