For that sort of money you could invest in a new Holbo Mk2 air bearing system, which includes deck and arm but not cartridge.
Forget gimbal versus uni-pivot. You get an extremely rigid tangential tonearm that floats on an air bearing. The arm is constrained on its bearing so that it can only slide bodily sideways, or rotate vertically. This provides an incredibly stable platform for the cartridge.
The platter also runs on an air bearing.
You can forget about anti-skating - it is not needed with tangential arms. Vertical Tracking Angle can be adjusted while a record is playing. Just as important for stereo playback, Horizontal Tracking Error is effectively zero, whereas most pivoting arms are up to 2-degrees out.
