i don't know why dms is so distant/silent. they have a good product that yes, can be better - mostly in the software flashing department, but i have yet to see a single official post from them. they're legit - their stuff does work, and they have chips for other consoles so they're not a little fly-by-night outfit, but they are strangely silent/distant. don't know what to make of it.
it seems "Team Xecuter" is more serious - they develop the most popular bioses out there, and their hardware seems to be robust (I haven't installed it) and they have a presence on xbox-scene, so although i'm happy with my xbit, if i had to do it again, i wonder if i would go xecuter.
i also like a lot of features of the chameleon, and especially their new solderless solution for the P & E points, but it seems to be they're a little behind everyone else...
