^Yeah, like others said, the appeal is the price. If it's a disposable amount, then what the heck!
I know how it is when something speaks to me in the world of cycling, so I'm not going to try and stop ya!
I had the same concerns that Greg mentioned. I remembered reading how one of the companies (BMC? Cervelo?) had experimented with overbuilding stiffness in parts of the frame such as the bb area, etc, and had reported that at a certain point things got way to stiff and had a detrimental effect on not just the feel of the bike, but actual handling, so they had to back off a bit for the final products. This frame, with the lowered seatstays, overbuilt chainstays, and a brake running through a relatively high stress area (
designed and tested on an exercise bike by a "frog" no less 
) in the seatube made me wonder. From the lack of data, to the misspelling of "money back GUAURANTEE", I was getting less trusting by the minute.
But then at that price... how can you complain? So now I am intrigued!
If you do buy it, please post pics! From a structural standpoint, it would be interesting to see how they ended up routing the rear brake. The drawings for the frame show it coming out the back of the seat tube in the area of the front derailleur, yet the pictures of what appear to be an actual frame show the rear brake near the bb under the chainstays.
Good luck and keep us posted! It could be a decent bike!
