That's a nice list of makers. Of course, I suppose the OP is looking for personal recommendations based on experience.
I have found Galco to be a very nice quality holster, and use an IWB thumbsnap rig fairly frequently. Another maker I recommend based on my own use is Simply Rugged. Rob can also supply exotic leathers and usually has a selection on hand. Hippo, shark, alligator, ray and elephant are common requests. Nicely tooled and /orcarved aare alsoan option with them.
