I have a red-tron frame and also one of those crystal frames (In white). Both with the respective straps.
Crystal/White frame/strap setup:
Looking to buy a sensor lens, or one of those frames for one of the Dangerous Blue setups or (dangerous?) yellow - the one with yellow splatter over black background. I'd be up to trade one of the previously mentioned frames for one of these two. Possibly add $$ from my half, just PM if your interested or have any other frames you'd like to trade.
