Opinions wanted for buying a new drill.

[keithdog]

I'm planning on purchasing a new 1/2" 18 volt litheum cordless drill for both home and work use. At work I use the drill mainly to install brackets and cabinets for fire equipment. Sometimes I will be drilling into cement walls or block, and occationally steel beams. This isn't something I do on a daily basis, but fairly regularly. I have it narrowed down to 3 brands. I'm leaning towards Milwalkee but I am also looking at both DeWalt and Rigid. It is my understanding that Milwalkee actually makes the Rigid brand. I was told that the Milwalkee brand is the only brand that uses all metal gears. I don't know if thats a true statement or not, but if it is, it certaily is one more reason to choose Milwalkee. Price is not an issue between the 3 brands, as they are each $199.99 at Home Depot for the same drill. Actually, the Rigid is on sale right now for $179.99. Milwalkee has a 5 year warrenty, DeWalt is 3 year, and Rigid has a life time warrenty plan. Not sure how much one has to pay for that lifetime plan if at all. Anyways, if anyone in here happens to know his drills I would appreciate hearing your opinion. Thanks
