Get a TT if at all possible. If you are willing to wait and do some intesive looking you will find the Supra you are looking for. I have a friend that has owned 6. The last one he bought was the one he had alway wanted. I own both a TT and an NA. I bought the NA first, I was really please with it. But when I drove a TT, I became really dissapointed in my NA. I started to go the route of putting turbo on it, but once I added everything up that I was going to have to purchase to do it right........it was just too much.
So I waited, and waited, and waited, then all of the sudden (1.5years later) I found what I was looking for. I bought a 93.5TT with 30728miles all original/ and all documented service.
The NA's are really limited to what you can do to them. But with the TT's the limit is your money!
Good luck and hang in there........
