Bonneville America Forums Forums Technical Forums Performance Mods Who do I get the CR racing carbs from?

I was thinking of upgrading my carbs to the Keihin CR racing carbs. Newspeedmaster has them http://www.newbonneville.com/html/cr_racing_carbs.html, so does Bellacorse http://www.bellacorse.com/bce024.htm, and British Customs http://www.british-customs.com/store/tri...arburetor.html. Which is the best deal, with what they include and price?
