I had pretty good luck with my Ryobi a few years ago. Then, last year, Home Depot had a great sale on their Ridgid Li-Ion kit. I bought the hammer drill, recip saw, circ saw, flashlight, 2 batteries and a charger for $260.00 brand new. It's worked like a champ so far, so I gave the Ryobi to my sister, and when I went to her house and used it, it started to smoke (It was over 4 years old by the way, and used everyday for over a year, under houses, in attics, everywhere a HVAC installer would go!!!).
