Just to add one more possibility to the list, George Merrill has come up with a new, no-holds barred turntable that I hope to audition soon (a friend of mine is the distributor, I believe), if only just to see what an old master has come up with. This one might be worth your auditioning as well, and it will be available for audition in the NY/NJ area, so it's within reach for you.
It's funny to hear people putting the Basis at the bottom of this list, as I think most of us would agree that it is an excellent table (that has served me well for over 15 years, I might add). The Ovation's (and I'm sure the Debut's) suspension, in particular, is absolutely superb at isolating the platter from vibrations, and with the Walker Motor Drive its speed stability is beyond reproach. That is why I feel that the other tables I've heard that I like better (the SME 30, the Transrotor and, of course, the Walker), while I can clearly hear that they are special products, offer what are probably, on an objective scale, comparatively subtle improvements. However, the subjective difference is what keeps me trying to figure a way to afford one of these beauties.
