Cheap MP3s for your car

Don’t want an iPod? No problem; for $30 you can play MP3 files in your car, using any USB memory stick. Where can you get this magical device? How about (drum roll)…. WalMart! Yep, the VR3 MP3 FM modulator (link) takes files off a flash drive and plays them. No word on whether it works well or not, but it’s a cool, and cheap, idea.
