I myself expressed a keen interest in the Japanese Market for DD TT's of which the GT 2000 was on my list, they were commonly seen and always from sale images looking in very nice condition.
I have duplicate and triplicate TT's of the models I did import , and no longer regret not importing the GT 2000 for Bearing Modifications, other Modifications, to be followed by non-modded / modded GT2000 Demo's.
I would recommend the 2000X but this will be towards $2.5K+. During my time of importing these were $800-$1500 purchases.
As a design, it is safe to say the GT 2000 is the Godfather of the Kaneda designs seen today, where the Motor Drive/Stator is directly attached to the structure that is now a Plinth-Chassis. (Can't but help think Panzerholz will night and day transform for the better, the original Plinth - Chassis)
Also, if you become an owner, do know there are Phosphor Bronze Platters to be found for sale and a YOP-1 standalone PS and a Phosphor Bronze Vacuum Platter Mat YDS-1.
If I did purchase, I do know as a sale item in the UK, I will have made substantial appreciation, if I could let go of being a hoarder and cleared out.
A friend has been a die hard user of BD TT's until a few years ago. They owned a substantially (Linn Spec' upgraded) Linn LP12 and a substantially modified TD 125.
One experience of a substantially modified (Bearing Assembly - Speed Stability) DD TT which was loaned, to be used on their system, was the influence instrumental in the individual replacing their BD TT's with a SP10 R.
DD TT's do have their admirers and advocates.
