I've found Minidisk recorders ideal for my own recording purposes. You can get a lot of MD recorder for your money these days. The latest one I have is the MZ NH700, and I either use the tape out from the mixer or use a Sony ECM-MS907 stereo microphone.
My computer isn't up to using the USB connection, so I manually record stuff onto my computer through the headphone output and the quality is more than good enough for my needs. You can use the optical output of equipment to record CDs and what have you directly into the recorder, if you don't use the USB, this is a handy way to get your albums onto disk, especially if you have a multi disk CD player.
