I think I would rather wait for an official, sealed in the box model with a full warranty. This device is not that great that one can't wait a few more weeks for.
as mentioned, an unbranded, unlocked device likely means it's a seed or internal device, which would be illegal to resale. the easiest way to tell if it's one of these is to pull up the help screen (ALT+EACE) and see what the vendor ID is listed as. If it's a -1 or 1 or 179, then it's a device that you don't want to sell.
