35 years commercial construction under my belt and have had probably every brand other than Harbor Frieght. Started out with some of the first, Makita 9.6 volt ala 1989/90 with Nickel cad bats which eventually went to Nickel hydride. Remember battery charging memory Lol? I still have those Makita dinosaurs and use them. I have a tile wet saw with a 3 1/2" diamond blade, and a cute little plastic water bottle on the side. It is the $hit. You can still buy batteries for them.
Now days I only buy Milwaukee "fuel" series or Bosch 18V core stuff. You Usually get what you don't pay for.
