I need a new set of hex keys. So, you've got your Pedro's and Park and Craftsman. But I ran across an Allen brand set that is made in USA, presumably Allen knows something about hex keys, and cost a lot less than the other brands. Is there something I'm missing here? At less than half the price of Park/Pedros it's pretty tempting for an occasional mechanic such as myself. I hate cheap tools, but good inexpensive ones are ok with me.
