DaJeeper, that is probably one of the links I read before doing mine
TimR, most surplus stores probably will. Best bet is to take your jeep and do a test fit to be sure you like the size they stock, as there are several available. I first tried a 25mm can, that was the same length and depth, but about 2 inches wider. It fit well now, but would probably be too wide if I ever get around to a set of aftermarket seats.
As far as getting to the cd player with the can closed... I doubt it. It could probably be done, but would require some thought and work. I don't change stations often, or swap discs much, so it won't bother me. If you need easy radio access, best bet is to pony up the $250 for a Tuffy.
