Well you're gonna need a lot of info on any modchip you're gonna get (i.e. wiring diagrams, instructions on how to flash the bios, where to get the flashing utility, what features the chip has, etc.). So if you can't find a lot of information on the chip now then I wouldn't pick it up. Get a big name chip like a Xecutor or X-bit. There's tons of information about those chips out there so you won't be left in the dark. It's worth the menail price difference to know you will be able to find information on your chip. These chips don't generally ship with any sort of documentation or instructions whatsoever.
Just my rambling two cents.
