My best guess is over 40, but I currently own:
Russco Cue-Master idler drive with Micro Seiki B77 MK11 and early Jelco arms
Micro Seiki MR-711 direct-drive with Micro MA202L 10" arm
Logic Tempo "E" with Logic Datum 2 arm
Gray ST-33 with ESL S-2000 (Ortofon) arm and Papst motor
One each Technics and Pioneer DD tables to loan to friends so that they can get hooked!
