Try http://www.brownells.com They show two speedloaders for the Taurus 66, one is by Maxfire and the other by Safariland. Check out the Maxfire concept at http://www.speedloaders.com; it is a little different that what you're probably used to. The Safariland is their COMP III (competition) model; check their site at http://www.safariland.com; if you don't see what you want, drop them an e-mail.
