Have about $100.00 credit (exchange) at Home Depot. Have 4 - 18 volt Milwaukee tools already - Impact, drill driver, sawzall, 6 1/2 in saw, and a 2 - 12 volt drills. I am thinking of the 18 volt vacuum, or, 18 volt 1 hand sawzall. Understand price differences and need to spend $$ for battery. Not afraid to spend more for XL battery for the vacuum. I've looked at the other options that I have in a corded type tool - Jig saw, sander. The vacuum or small sawzall would be my choice of something I would use more of. Most practical.
