there are lots of great strap makers out there- i have been very impressed with some of them, especially some of the really gnarly ones from strap culture.
However - i would take a look at HKtan - it will take a good month to get the strap - BUT, you can tell him exactly what you want, in exactly what color, thickness, hide, length - whatever, - and thats what you get. - and considering the rising prices on all those sites - his prices are VERY competitive, if not way better than alot of those other sites.
plus he must have 200 examples of straps he's built already http://s32.photobucket.com/albums/d25/HKTAN1/ password hktan if nothing else, its a great way to see whats out there cause the variation in selection is paralleled by no one.
me personally i like really thick straps - so i have to either get it custom - like V or HKTAN or get the even more expensive premade ones from like strap culture or some of the other newer sites that have popped up.
for me, i don't mind the wait - i have lots of other watches in the collection to wear till the strap comes in or the crystal gets back or whatever
