I thougth they lowered the cost for the CHL during the last session. I know they removed requirements to retake a renewal course everytime the licence is renewed.
I renewed last year, still had to take the classroom & range training, IIRC it was right around $125 for that. The renewal fees to DPS was less than the initial permit, but I don't remember what it cost right now.
I've done some OC in AZ & KY, really haven't had a problem with it hanging up on anything. And a 4" .357 sort of sticks out there.
