I'm pretty dang happy with my 20v Dewalt stable of tools. Easy to find in the stores or online, many different tools available and reasonably priced.
I have stuck to this brand now for several plus years and have 10+ that share several batteries. I don't use them daily but I expect them to last as long as I will be using them. Hate to think that most all the tools I am buying now could be my last of that type. I guess that is a good thing because at some point a fixed income isn't going to support my habit.
