If your thinking of a higher end set of caps, I'd highly recommend "CueCaps" / Alton Takata. His work is top notch and often spectacular. Alton is a true gentleman too. Have misplaced his website but I think you could google it or PM CueCaps here.
Jim Baxter is great to deal with...he just did a set for me...he does great work at a good price...you can check out some of his work in the cue gallery section
