Brent,
Lot's of replies for various decks. Can't say one way or another which is best. But, I would like to interject. If you are not looking for absolute performance (and I can only assume you are not if you are looking at cassette decks), I would suggest looking at a cassette and a R2R that match each other. My go to pair would be a Pioneer RT-909 and a Pioneer CT-1250. Neither of these decks is the best in their class and neither of them will be a bargain. But they can give you decent performance and they'll look good doing it. At least that's my opinion.
Good luck however you proceed.
