Happy to see someone else with an interest in the gunbelts. I have the above belts too, plus the Todd belt and untill recently also the Lost-Ark belt.
So far only the Noel Howard belt has been able to live up to the standards I expect from a Raiders gunbelt. I wont say the others isn't worth the money, but they are very far from the quality that Noel Howard provided. The Keppler belt is the only one I havent held in my hand so I cant say anything about it.
As a result I have had a local leather expert cut some belts for me and I'm really looking forward to try to make some belts myself. My MBA belt is still the undisputed champ, but I use my TAG belt and my new Todd for everyday use. When they break in they win a little however.
If anyone in COW knows where to find screenaccurate gunbelt buckles in europe I would really like to know about it. I have contacted Noel Howard today and hope he will find time to help out on this one.
Here's a few Todd's for comparison:
