Idler wheel drive vs Belt

I noticed in the last day a frenzied bidding on an EMT 930 (plus arm/cartridge, etc) that went for $6.5Gs. Lots of money for a vintage kit. I also read some laudatory comments on the venerable Garrard 301 with boutique plinths. Anybody out there have experience with such, and can comment on whether I should abandon my purchase of a Teres and go for a 'transcription' turntable like Garrard 501 (with Schroeder DPM). Those vintage designs have lots of torque as they were used in radio stations, but don't seem to have close tolerance bearings or heavy platters. Yet some have thrown some serious positive comments on these vintage solutions. Is the magic real, and what contributes to it?
(I am not going to blow $6G on an EMT930 any day soon).
