My LBS sells them. Has had major problems with the individual PureFix wheelsets that he has sold, and all 3 or 4 of the customers that have bought complete bikes have come back with various problems not caused by user error. I probably wouldn't bother, especially for the price. My LBS is selling the rest of their PureFix cycles and replacing them with SE again.
On a lighter note, any issues that the shop has had with the cycles/wheels, PureFix was happy to remedy the situation. Good customer service should not go unnoticed, it just seems like the quality of their bikes are kind of subpar.
