I was somewhat in the same boat last year. Got the itch for a new TT.
I have a MoFi Ultra deck with the MoFi phono preamp. I felt I could make the next major jump in many areas if I picked up a newer, more expensive TT. What I ended up doing was adding a Hana ML cartridge and a Parasound JC3 Jr. I am very pleased with the results. Everything is in such tight focus, more open and smooth sounding too. Now I feel I'd have to take out a loan to make any major improvement. I guess I'll have focus my upgrade(itis) elsewhere.
