I am a fan of Milwaukee power tools. Here's what I have and love.
I own
this drill personally and I love it. It's plenty powerful.
I found
this kit for about $250 last year. I bought it for my team. It was a great deal. You'll need to keep an eye out for sales.
I found
this set for $100 on black friday. It came with 3 batteries. I bought it for myself.
Finally, I bought
this circular saw over the summer to help build a deck.
With Milwaukee tools, I'm confident I won't need to purchase new tools for a LONG time.
