I bought the Makita impact drill, plows screws. Best impact drill! I bought the cheaper one (200$) that's white, charges in 15 minutes, lasts around 3 hours straight if I recall correctly.
As for circular saws Mikita, DeWalt, and Hitachi are my favorite. The only reason I didn't get a Mikita circular saw is because Lowes don't sell them.. I ended up buying the Hitachi, strong, inexpensive, durable (so far still good). I don't like the Hitachi blade, not used to it much I guess, fish tales a little. I'm a DeWalt construction blade guy lol.
I'm going to buy a reciprocating saw, either the Milwaukee super sawzall or a Mikita AVP (I heard mixed reviews about the Mikita AVP though..) I only use Milwaukee.
I only like corded tools. Cordless, I will always use Lithium Ion.
