So many great golden era DD tables out there, what do you recommend for $1000?

A comment on the "bi-directional servo":  The TT101 (and the TT81, if Halcro says so) certainly have exceptional speed control, but when JP Jones eventually fixed my TT101 and got it working, his comments on the "bi-directional"-ness of the servo were of a skeptical nature, if I recall correctly.  (One would think that the term indicates the platter is not only speeded up, if too slow, but also retarded, if its running too fast.  Not sure that really happens.) I cannot recall the specifics; maybe JP will comment if he is around.  Anyway, it doesn't matter, because the point is that the system works superbly although very electrically complex.

@halcro   Thanks.

 (Mine came with a DA307 tonearm, which is sitting in a shoebox somewhere.)

Don't underestimate that arm to be considered junk.
It is an excellent arm with a still low price on the market, it has not suffered the costly folly of many vintage pieces and is better mechanically and constructively than vintage arms that are now overrated and sold for hundreds and hundreds of dollars.
I don't want to mention names so as not to hurt the sensitivity of some owners but I want to give a small example of many positive features of this tonearm (there are several):
the rubber that separates the barrel from the counterweight of the DA307 even after 40 years from its construction is perfect if you look at it. does not crumble, does not break and is still perfectly elastic .... how much rubber used in audio products is so durable?
