g0tr00t,
if you're willing to do some soldering, tons of Prism cards are all based on the same design which has pads onboard to solder on an external antenna jack. some of the cards in this lot can be had for $30 if you look hard enough, and although some retail for over $100, they're really all the same stuff inside.
i got the drivers to load fine w/ RH7.3 right out of the box.
