For a "cheap" hand-held scoop (the kind that will cost over $30.00) I went to a tack-and-feed shop, bought a 2-quart plastic feed scoop, and drilled a lot of 3/8 inch holes in it. It ends up looking just like one of the expensive "hand held sand scoops," is just as sturdy (they were designed originally to hold several pounds of feed), and cost me about 1/10 the price!
My only problem with it is that I didn't drill enough holes to begin with, so the sand filters out too slow. Easily corrected by drilling more holes. Just have to be careful to maintain the integrity of the shape, and leave enough plastic to keep its strength.
Even cheaper would be to make one like my first sand scoop -- I cut an old laundry detergent bottle to the shape of a scoop (keeping the handle intact) and drilled a lot of holes in that. Cost: $0.00, but the plastic is so thin that it isn't very strong. Still worked okay, though.
Just remember: expensive doesn't always mean better.
