I got a pair of these at Walmart. They are made by Wells Lamont. So far, I really like them. They keep the sun off of the back of my hands, help with gripping the scoop, and I don't get calluses on my scooping hand anymore.
Update 6/11/10:
The left hand glove now has a hole in it near the thumb. It turns out that these gloves are made of cotton. I like the style but will have to find some that are made of a sturdier material.
