The ps-x50 is a very good sounding TT - a friend of mine had one that broke down because of the automatic features (REJECT, etc.) I opened it up, and literally tore out the linkages which do the auto stuff with my bare hands - leaving it as a 100% Manual TT. The thing sounded GREAT after that! You could consider trying that before spending any money. I've been tempted to get one myself and do the same thing.
As far 250 TT's goe, I'd recommend a used Technics 1200 or a used Dual CS5000. I've had both and they are very acceptable sonically.
