^^ Nice sorenson belt there (it's got the same buckle as my Unlucky belt :P).
I asked him a few months ago whether he would consider doing a belt heavier than 10 oz, but got shot down
How thick is the leather on yours?
I really would recommend Unlucky (Scott's) belt!!!
If anything, other than his great handiwork, the ability to customise the belt and incorporate rivets into the final make-up is just awesome - not to mention you get your pick of leather weights.
Also, Corter seems to be doing some great stuff, but I've never owned a piece.
For those living in Asia (especially Taiwan), check out "Ken's" belts or one of his collaborations with a denim shop called 'faith'; Angelos also does some really nice pieces - his hand-craft is on the same level as Red Moon and The Flat Head, if not better.
Obbi Good is another great one - check out their stuff on the mynudies thread. Really clean and novel designs, the burnishing is always superb, the hand-stitching neatly done...
And finally, if you want the most uber natural leather on the face of this planet, check out the belt thread on SuFu...will have some pics of 15oz+ oak-bark tanned leather belt by Terry coming soon.
Of course, there's always the Japanese brands to fall back on. For a great bang for your buck, I would suggest avoiding expensive names like Red Moon, Samurai, The Flat Head, etc...go with KC's (they make some of Samurai's stuff), Dolce Vita (house brand of Clever, excellent crafting and choice of leathers), Kawatako (for some very well made Tochigi leather), etc
So yeah, either buy them from a private leathercraftsman or a specialised leather company - better value, higher quality.
