Although there is a plethora of good holsters out there (and I've tried a lot of them) here's 2 links of some of the many holsters I currently own and seem to work well for me.
Mernickle Custom Holsters - Performance Series
El Paso Saddlery - Strongside
Currently have the EPS #88 and 77 (thumb break) but the Sky Six seems to ride higher.
ETA: Also have had good luck with sour dough pancake.

The Don hume listed is a good holster IMO and I plan to try a Lobo in the near future.
