I'd say $125 is a good price for an M-30, and $225 is a good price for the M-308.
Also, I had another post that just went "poof" on my computer, but it went something like this: [rewrite]:
For a mixdown medium, it sounds like "something/B/C" is referring to "Off/Dolby-B/Dolby-C", so I'll assume you have a DolbyB/C cassette recorder. If that's the case, then you can mix down from the 4-track to the cassette, and that's probably most convenient.
Also, replacing cassette decks in the marketplace are the CDR/W standalone recorders, of which there are many to choose from. They are very popular with the cd-seeking crowd, who doesn't want to record on the 'puter.
Likewise, a less popular mixdown medium is the Minidisc recorder, mostly touted by Sony, but other mfr's like Sharp may have MD recorders. However less popular MD is, it's still out there, if you look hard enough.
Worth mentioning, is that a lot of analog recordists are recording stereo mixdowns to the 'puter in wav file format, and burning cd's from the 'puter. F/I, I do that. All it takes is a RCA-to-1/8 Y-cable adapter from your mixer output to your soundcard input.
More, if you're seeking a cassette recorder at this time, they may still be found new in the stores, but less as time goes on.
If you are not averse to used gear, a favorite of mine is to search Ebay, "Technics cassette", and this will pull up a couple pages of Technics cassette decks, of which the DBX-compatible cassette decks are my favorites. I prefer cassette decks that sport "DolbyC and DBX", such as the Technics RS-M50X, RS-B57R, RS-955, and other such more "modern" late-80's Technics cassette decks.
