Why not go back to the well and try again with IRO? I guess the time of year may be off, because as I recall, Tony said that he wouldn't do another group buy that ended in the middle of his busy season (just as summer was starting). It might be worth contacting him, though.

As for Soma, they make a good frame, but how low can they really come down for a frame and fork to make it worth our while? In a few months, Bikes Direct will be selling a Kilo TT frameset made with OX Platinum tubing for "at or less" than $300, which is a better deal than I think Soma could possibly muster, for what amounts to essentially an equivalent bike.
