I use audiograbber to record, from cassettes and discs, then audacity to clean them up afterwards. Works like a charm and both free!
As mentioned above, feed into the line in sockets (I go from amplifier line out).
You can eliminate the majority of the hiss of cassettes with minimal (audible) loss to sound quality.
Once in your computer you might then wish to transfer to cd (not sure about copyright rules) for convenience.
