While not the cheapest sporrans out there, Buzz Kidder sporrans (which I believe are made in the US), are large and well made out of thick but supple leather. Many XMTS vendors sell them and quite a few of us (at least we "old timers" 
) have them. They are built to last and the nice thing is that 2 or 3 years down the road you will still use them and still like them.
