I'm raising this thread from the dead to let you guys know that the ads rdx-155-ef fm usb radio thingie has a $10 dollar rebate on it over at Circuitcity.com, thus bringing its price to *free* after rebate. The rebate ends 12/31/2010.
I'm thinking this is a good way to get a usb radio to play with. I do not know what support it has in the various front ends, etc. I cannot vouch for the quality of the radio either.
