Hi, I'm looking for a new VCR to replace my broken Sony. I'm not looking for top of the line, just something to time shift off the air programs. I'll be taping sports programs such as football games, etc. This means that I'll do a lot of slow speed taping to fit the whole program on the tape. I notice some manufacturers push 19 micron heads and Panasonic touts their DynAmorphous metal heads. Any recommendations?
