I have three frames painted by CA, a Sachs and a Rivendell Road Standard, as well as a Lemond that was touched up and clear coated. All three are exceptional, investment-quality frames, if such a thing exists.
Al Wanta has painted four frames for me, three Merckxs and a Serotta, all were done exceptionally well, no complaints, very reasonable prices, about a three month wait time and a genuinely nice guy.
