WeirdStuff has tbolts, no case, no info about firmware version, for $75. They were $495 but I sent them a note saying it wasn't a competitive price and they lowered it and they appear to be selling out quickly. http://www.weirdstuff.com/cgi-bin/category.cgi?item=29654 Also on their weirdstuff-inc ebay store for the so inclined.
