I don't know of any retail versions, but they are available on ebay. I have not posted any but have a couple Virgin VM0500, Motorola m500, Go Video Rave-MP ARC2.5/ARC5.0, and Rio Carbons, any of which you could get for around $50 or less depending on model. All but the ARCs, you can download and install the firmware yourself, the ARC, I would have to image the drive for you, as no firmware is available. ps... new to this board today, not trying to sell anything, not sure of the rules, just trying to answer some questions and learn some things....
