Buying a tool isn't good enough - you have to buy the right kind. A rubber mallet won't suffice when a carpenter's hammer is needed. A hacksaw won't cut the mustard (or anything) when a table saw is needed to rip wood. If you go to your local home improvement store expecting things to be easy, forget it. The tool manufacturers know the demand for handheld electric tools is so strong that they can saturate the market, and still expect to turn a profit. Witness all the cordless drills out there. It does help to know which style of electric sander to buy
, before you get into the more difficult decision about price, brand, color, etc.
