Over the past year I've installed and repaired quite a bit of drywall while working on the house. I feel like this purchase has paid for itself after just a few jobs as it makes the often not-so-pleasant job of cutting drywall (especially in renovations) much, much easier and quicker than hand tools. It kicks up some dust, which can be reduced somewhat by moving the tool one way rather than the other. The build quality is very solid; I'm not worried about that aspect of the tool. I make sure to blow it out with an air compressor after use because even though it has a sealed motor, drywall dust is best kept away from all sorts of moving parts. With a board screwed to the wall, you can easily cut long, very straight lines yourself, which is also very practical. One last thought; I'm much more comfortable with it when remodeling than with a hacksaw. Crashing into walls without knowing what's behind them, even with the best guesses, is serious business. Since you can adjust the depth to match the thickness of the drywall, the risk of damaging electrical and data lines is virtually eliminated, which I think is a big deal.
