Cheap is quite subjective....

The Stillwater does have a great nylon cargo sporran as other folks mentioned.

I have one of Stillwater's 3 tassle sporrans. Personally I wish I waited to buy a Buzz Kidder. I eventually got a celtic knot Buzz Kidder (from USA Kilts) and like it alot better. The BK is slightly larger and has much softer leather. To me, it's worth the difference ~15 vs 50.
