Quality will degrade if the cassette is exposed to magnetic fields. You also don't want them exposed to extreme heat or to dust. Heat can warp the case and dust can act as an abrasive.
Don't buy a cheap dual-transport deck. Get a three-head deck that has a bias adjustment for recording. You'll be very happy with the quality from a good deck, provided your tapes are well recorded.
