I'll second the suggestion to look at Lobo. Ray's a member here and puts out a quality product, and like Samwood said, for a fair price.

There's something I learned from my grandfather when it comes to tools--and a carry holster is a tool--never confuse inexpensive with a bargain. Most of the time you'll end up dissatisfied at some point and buy the better quality you should have in the first place, and pay for the same real estate twice.

For what it's worth, a nylon holster seems to eat up bluing at a faster rate than a good fitting leather one.
