Anyone have one they recommend? I've seen some $30-50 types for sale at Amazon and the like, but wasn't sure of the quality. I don't like using a screw driver to compress my pistons and will be changing my pads between race and street much more often this year. I've seen some obvious high quality spreaders, like Girodisc offers, but I'm not about to spend $250 on one. $50 is about the most I'd like to invest. Let me know if I'm off-base here.
