Walmart carries a nice 1.75" wide leather belt that looks good with my USA kilt as well as my UK Survival. Black or Brown, sort of Pebbled finish with a brushed nickle buckle. It won't accept a large buckle but it keeps the look simple yet rugged. The price is only $11.00. I actually bought two and am trying to make a sporran strap from the second. I expect the Belt sporran and strap to look very similar.

I couldn't find it on Walmarts site but it looks similar to this but with a textured finish.
