A supply house had a flyer I picked up and was paging through...
Milwaukee M18 mixer, Trade in a corded mixer and get $100 off a kit that has the mixer, 2 - 5 amp batteries, charger and a carry bag.
I traded an old 1/2" drill motor that I have used to mix concrete and repair mortar. That thing was probably 35 years old, the guys were using it one day mixing something too stiff for the drill and it started smoking.
I told them to leave it alone and we'd figure out another way to mix the stuff up. I come back a few minutes later and the one guys says "Drill no work." When I got into the shop that night I took it apart, the brush holders had melted, so I heated them back up and straitened things out, it's worked ever since, you just can't get it too hot.
Well today I traded that old dog in, I was kinda surprised they would accept it as a mixer, but I carried it in with the paddle chucked up.
Pretty good deal, out the door with tax for about $265.
