Amey had some s100 cranks for sale... and a cheap option for gxp when using single speed will be an apex/rival crankset run with a single ring (this is what I am doing)
s100 are powerspline right? I might get in touch and see how much he wants for them.
Another option is On One Track Cranks but they're pretty ugly
