I bought a suede pair of shotguns by Bob Blackwood. They suit me for schooling colts and general ranch riding. They were very inexpensive and have held up for two seasons so far. Had to cut off a foot at the bottom because I don't need the equitation look while working in corrals.
I'll be wearing them this fall and plan on spraying them with a waterproofing agent for fall work.
Sure, I'd like a pair of custom chaps, but that isn't in the budget, nor have I found a need to kick out > $300. I couldn't open your link, but I'd give it a try.
