If you want leather, check out ubgholsters.com and kdholsters.com, both Nate (UBG) and Kevin (KD) make nice stuff at a reasonable price with fairly quick turn around times.
If you're interested in Kydex/Kydex-Leather hybrids, I'd say check out crossbreed, tucker and comp-tac.
For "off the shelf" try, Galco, highnoon, desantis, don hume etc...........
