I don't think the firmware on the Tbolt makes much difference in performance. (The older firmware even has a couple more features in it).
Units with the 3.0 firmware are newer and have a much greater chance of having the poor temperature sensor which definitely has a bad effect on performance. If I had my choice of two units (both with the good oscillator) I'd definitely pick the older one.

-There are several cheaper ones for sale but make sure you get the 3.0 firmware
