As most have said, lithium ion is the way to go. As someone who uses cordless tools a LOT, I've always been a Porter Cable fan.
I feel their quality has started to slip, however. At this time I would recommend to anyone wanting to buy quality to get Bosch. Hands down the Bosch tools are the best out there at this time.
Never have been a DeWalt fan, they were really the first of the tools made to the price point that the big box stores demand. Decent tools, but not the quality of the old Porter or the Bosch.
I agree. IMO, Milwaukee always made the best power tools, then like all the other manufacturers, they went overseas for most of their production. They still make some very good tools, but I find overall that Bosch has the best power tools these days. The old Porter Cable tools were also very good.
It's a shame how tough it is to find quality tools now. Several years ago, you had to pay more money to get the good made in USA tools, instead of the cheap/terrible made in China tools. Now, you can't even find made in USA tools! The good news is that the made in China stuff seems a little better, but not even in the same ballpark as the older made in USA Milwaukee and Porter Cable.
I think that the manufacturers just saw this as a straight price-point play, put these Chinese/cheap foreign made tools in the big box stores, and we'll sell way more units than the more expensive made in USA/German tools. Power hand tools are now just like a lot of other things in our country; disposable junk. It's a shame for people that don't mind paying for quality. My theory is to pay more, but buy it "once." I suppose for the person that is going to use their cordless drill for a lifetime total of 23 minutes, that does not register! Again, I hate that I don't have many choices to even be able to buy quality...
I know a lot of people like DeWalt, but to me they are ramped-up Black and Decker tools. They are ok, and their made in Mexico line is better than a lot of the made in China stuff, but I think there is better out there... Bosch has some of their products made in Austria, and the quality is good on those. Milwaukee has some some stuff made in Eastern Europe that I've had good luck with, as well. The Hitachi tools are also ok, better than a lot of others.
This has been my experience, YMMV.
