3 head cassette decks

There were some but the Japanese were notorious for not supporting their products in this field and parts may be impossible to find. Tandberg and Revox offered very high quality decks, I will have to check my old mags for others.

Teac VX series, Harman Kardon, Denon, Technics PRO series.

Look for the better model Luxman, Pioneer, Akai or Aiwa. They can be had dirt cheap, but as pointed out above maintenance/repairs can be a problem.
