I use 18v DeWalt tools with cheap aftermarket NiCad batteries. I was without cordless tools for about a decade, but in 2018 or so I saw a well used 8 tool assortment with 2 chargers on Craigslist for $150 and bought it, and now I use some of them every day. If the drill or the impact ever die I will try to replace them, since I've gotten used to them and find them handy. I think that platform will go on for a while with aftermarket support since it was pretty popular in its day.
