Worst piece of dogs doodah I ever bought, a long time ago, was a Sanyo BETAMAX
Looking at the recorded playback was like watching TV when you`ve had more than a few double whiskys.
Luckily, because of the crap picture, I managed to get it changed, and I picked a VHS model. As it turned out, VHS flourished, and Betamax just faded into oblivion.
