Since you're starting from scratch, you'll get the most bang for your buck buying a kit.
This one's got it all. The drill is first rate. 495 inch pounds of torque. The sawzall is an awesome, no compromise new design. The radio has no equal in sound. The circular saw is left handed, so it makes a perfect compliment to a right handed corded saw. That's a very fair deal on that set, and they're built to last.
I mentioned before that you can get a
comparable Ridgid set for a comparable price, and is lifetime warranted if you buy before December 31st. That includes the batteries, which are very expensive.
I own the Milwaukee set, as well as the
corded 1/2" Magnum Drill and
7-1/4 in. Circular Saw with Tilt-lok Handle & Brake . I also own a cheap saber saw, and Porter Cable orbital sander which are used quite a bit.
The Milwaukee kit with the hammer drill, sawzall and radio is a great start. The Ridgid set sounds like a smart buy with the lifetime warranty, but I don't care for their recipricating saw at all. Might be better to just buy their cordless drill and go with Milwaukee's
corded Sawzall. Don't bother with the cordless circular saw unless it's thrown in with a kit.
