You can pick up a set of Narex Bevel Edge Chisels with Wooden Handles from Amazon for $62.99, which includes one ¼-inch chisel, one ½-inch chisel, one 13/16-inch chisel, and one 1-1/32-inch chisel.

A chisel is a very basic hand tool and has a specific job. A 3/4-inch chisel is a good all-around width to have if there's only going to be one of these tools in a homeowner's toolbox arsenal.
