I also have a Ps-3t!
So i guess Performer series and today's js 32 must be similar in general. The performer wood is better, but the problem of the ps3t is the location of the imput jack, that makes it less confortable. Todays Js 32 (rhoads) have the inpit jack cavity in the higher wing.
The system of the screw of the whammy bar is better in the js32. I also like the warrior a lot, but in my oppinion the rr is confortable to play seated as well.
About the entery level in the 90's, was not really the performers, there were a cheapest model: js 20.
