I second Dutch's recommendation. So far, I like the DeWied brand best. There are a number of web sites out there that sell them, so you might shop around, taking shipping into consideration of course.
Other local sources for me at least are:
Bass Pro Shops
I prefer the DeWied, but if in a pinch, I can go out to these stores and get a package.
