My ten cents worth on tape type... I've been buying bricks of TDK SA-60's which seem to work well. Then I saw the TDK SM's at music stores sold as multi-track masters - more money, but still pretty cheap. So I actually called TASCAM customer support to ask, as I was working on a project that was very important to me. When I finally was able to talk to a rep,it was almost as though he didn't understand the question. He wasn't familiar with the high-end TDK SM's (which I thought kinda weird) but basically said to use any good quality type II high bias tape, 60 min or less to avoid shredding, and to CLEAN THE TAPE PATH JUST ABOUT EVERY TIME THE MACHINE IS USED, of course allowing time for the fluid to dry. He thought the BASF formulation for the bulk cassetes from the catalog was weird, and hadn't heard about that either. I think the SM's sound better.
