A few years back, Radioshack was selling a receiver that was specifically set up for CD-Tape-Record-Axillary. Sure, you could hook up multiple tape players, or what have you, but it was one of the few receivers that presumed a person was looking to set up all three.
Needless to say, I bought it because it was under $100 and my old receiver hadn't been working for some time. Sure enough, I set it up for my record player, my tape deck, and my CD player. Point being, I guess enough people still use that set up for Radioshack to sell it in the first place.
Only problem is that while the pre-amp for the record player sounds phenomenal, and the CD player is in good shape, the tape deck is touch-and-go, and I don't know if it's worth fixing...or even possible to get fixed anymore. Cool thing about it is that (when working) it can record anything being played on the receiver, whether it be AM/FM radio, the record player, the CD player, another tape, or anything installed in the axillary.
That said, I can't see cassette tapes having the appeal they once had, now that digital recording on computers and digital "walk men" make the process more convenient.
