I love DeWalt!
They have a lot of power and are very robust. Cordless is the way to go, if you're buying tools. However, except for the drills, the other cordless tools drain batteries really fast. Their angle grinders, reciprocationg saws and circular saws use up your battery power fast. Also, their cordless drills are all unusually heavy, which makes it hard to drill holes accurately. However, you can't beat the quality of DeWalt tools.
