Grabbed one similar to this while at the lumber yard a couple weeks ago, just on a whim (this is a stock photo). It was on sale for $25 and I'd ever had one before, thought I'd try it. The concept is GREAT! This one works fine, but I've been looking into them now and they are priced all over the map - 7 or 8 dollars up to over $100 for a rechargeable one. MrsWD grabbed it and uses it for sewing when I'm not using it in the shop.
I'm thinking of getting a more powerful one for myself, as I could use a little more light than this one puts out. Anyone else use one that they recommend?
