Old Newbie- Planar 2 vs MMF 3.3 vs MMF 5.1

Hi, just getting back into vinyl and have it narrowed down to these 3 turntables. I want to keep it in the $500-$750 range for a new turntable and can't find head to head comparisons to these 3. Previewing in person appears to be impossible as the only dealer within 100 miles stocks only Rega and usually has all the doors open...with lots of traffic going by. Go figure.
Also, I'm running this through my old Yamaha A1 Amp.Planar 2 with Carbon CartridgeMMF 3.3 with Ortofon Red Cartrige
MMF 5.1 with MH Magic 3 Cartridge. (open box closeout brings it in the price range)
Or should I just throw a dart!
Thanks.
