I have the Classic (which is a reissued B) and it's fun to play with plus it sounds superb... The new TI looks very interesting (plenty of control, ideal for a software based home-studio), but I'm not sure about the price - I think they're still pretty expensive... No matter what you choose, satisfaction is guaranteed - after all, it's made in Germany and could almost be described as the BMW of synths - solid, stable, good-looking and a pleasure to use... ;)
