I use Arca-Swiss type quick release clamps and plates from manufacturers such as
Really Right Stuff and
Kirk. While they are nice and all (fitted to individual cameras and lenses), they are also quite expensive.
The little universal ones that come with Bogen/Manfrotto, Gitzo, etc. suck. I wouldn't bother using those. Save your money if you can only get those. They're a pain in the butt to keep on the camera without it shifting, and not particularly convenient in operation; they cost extra, but I don't feel that you gain much by having those crummy quick releases.
