EverDrive - MD/Genny flash cart

Did a search to see if a thread was already here for this... Found nothing.

Why this is interesting over Neo/Tototek carts:
Uses SD/MMC media. (FAT16 - currently 2GB max - can be updated in the future via SC/MMC slot for FAT32 and HC media)
Writes and loads saves direct to the removable flash media.
Price!

Don't know about vendor reliability/honesty, or longevity of support.
I know this won't run Virtua Racing or Super Street Fighter 2 (pretty much a given). But I can't find a compatibility list at all on the site, or off.
Only .bin roms will work right on the cart (off-site source, assembler boards) .smd cause problems because of how those roms are extracted and built.

Does anyone here have one of these? I'm seeking information, references and opinions before I even think about sending someone a money wire transfer... Can you get this thing from someone that takes a service with buyer protection like paypal (which he says that he can't accept, living in the Ukraine)? Any insight is much appreciated!

Quick edit in here: I'm interested in using this to play sound/music files that I would be composing and building myself along with it's other uses. I've seen the demo vid where it is running extracted audio files from carts/roms through it's module function. If anyone has any experience with that aspect, I'd love to hear about your experiences with it.
