This was brought up a while ago by someone here but I just can't find the post. So I'm bringing it up again. GDEMU is a hardware emulator of the Dreamcast GD-ROM by the Makaron dev. Though he's finally started selling boards, the first run is sold out. He builds each one by hand and has been having a hard time navigating the web of customs bull too, but he says he's looking into options. A second run of these marvelous things seems likely, at least. They currently go for €100 each. EDit: It just occurred to me that this might've been better in Technical Discussion.
