If you know what you want it might be cheaper to get it painted on. I bought the UJ Mirror caps from the dealer and it cost me $300
If I had of known in advance I would have got it airbrushed onto my white ones I have!! If your really keen, I know you said you don't like e-bay, but america has them on their all the time, chrome, black, even red with the Superman symbol on it!! It depends on what ones you want. But if you want a design I think the dealer will sting you unless they have come down. I paid $80 for the UJ interior Mirro back cover which I didn't think was too bad from a dealer!!
