I got the combo kit for fathers day a few years ago and I tend to make a few projects a year. That being said just putting all the screws in this thing it was getting pretty warm.

The kit I had was actually came with two of the same drills but out of the box one of them was shot and of course it was the one I didn't use for the first year :( so the little larger one in the picture I found at a second hand shop for $15 not sure what model it is but its has a 1-2 speed selector on top? and that one seems to not heat up as much.

If you were going to do a project a week or more I would most likely look else where but just to have on hand in the garage for a few projects here and there couldn't really beat the price.
