Gene Poole, if you still desire a well cared for SBM-1, with all original packaging, adapters, receipts etc I have one that's been stored zipped for years, have recent pictures if requested.
Priced to move...
Have a couple of 7 pin adapters also.
Still have a PCM-M1 but I am keeping that for transfers if my other two rack DAT units don't behave.
All the previous posts give great advice on options depending on your personal preference.
I patched a Sony D-8 DAT out of my SD722 for Peach Fest all last weekend for someone and I forgot how solid and heavy a unit that is or was(sold mine years ago) compared to my plastic M10 that doesn't even accept a digi signal(sigh).
Even saw a taper run a Sony D-5 cassette deck all weekend, people were stopping and taking pictures. Said he hates the digital sound and prefers the warmth of the analog sound compared to 1's & 0's, but tough to find good cassettes these days.
Haven't seen a field HHb field CDR out in a quite awhile...
