Don't forget the venerable idler drive, Ben. You can get Lencos and Garrards for a lot less than a Gyro, especially the Lencos. You could get a Lenco 75 and service and re-plinth it, all for less than £100 and I think you would be very
pleasantly surprised by its performance when coupled with a nice unipivot arm or even a lowly RB250, or suchlike.
I run a Goldring GL88 and it is extremely pitch stable, rumble free and I sold a DC'd Gyro/Orbe in favour of the GL88. Very easy (and fun) to set up, tweak and modify if you're into that DIY side of things (see here
). No electronics or ICs to worry about. Pure solid, bombproof mechanical design with a high speed, high torque AC motor to drive the music along.
Just a thought.....
