I'm a big fan of JM Custom Kydex holsters (from Tony Mayer). I like the claw for AIWB, that's the only way I've been carrying for a while now. In my opinion of all the holsters I have tried his are the best.
If cost is an issue, keep an eye out for a second hand one that has not been modified. Lots of people flip holsters trying to find comfortable ones for them. JMCK holsters will hold their value better than some of the cheaper options too in case it doesn't work out for you.
