I bought an unbranded m001 from ebay and was browsing the forum in all its various states over the past few weeks in anticipation. I finally got my hands on the m001 and after upgrading the firmware (currently using ECOTOX v1.0), I've found it to be a very usable device if all you want to do is explore and have some cheap techie fun. Having said that, I certainly wouldn't consider using it for business or serious use...
