Another Dewalt fan here. I've got a 18v drill and impact that I've beaten the crap out of here at the resort. I'd be hard for me to buy another brand.
Milwaukee, de Walt, makita are all great brands. Most of my power tools are makita and I don't have a complaint about any of their stuff, it's all lasted me years so far
Don't forge to check out the new Ryobi stuff. Dewalt is nice, and I used to only use Dewalt products when I worked in construction and was using tools 8 to 10 hours a day (or more) and my income depended on my tools. I recently bought some of the 18v Lithium tools and am pleased with how they perform. They are holding up well, and I've yet to run into a project the drill, driver, recip, and circ saw can take care of. Just my 2 cents.
