Probably 25 years ago I switched from Makita to DeWalt in the shops. Dewalt made the best cordless tools then. I think Milwaukee corded tools have always been as good or better than B&D/Dewalt. Not sure when Milwaukee even got in the Cordless market. Now Milwaukee has cordless everything. And I really think they have outdone Dewalt on most of them. I gotmy first M18's over 10 years ago and have been hooked since. I don't see much difference in battery life between red and yellow (with Li anyway). That said, If you really want 'disposable' you might do more bang for the buck with Ryobi. Cheaper than the other 2 and decent power.
