I got the Milwaukee circ saw for about 130 bucks, tool only, as I had the battery that came with the grease gun and I'd bought an extra because I was too dumb to figure out how to plug the first battery in all the way. I used the saw a couple times this weekend. When I pulled it out of the box and got the blade on and all that junk, I fired it up and was disappointed. It sounded like a kids play-saw. It didn't seem to spin the blade very fast and I was curious if the battery, which was on the unplugged charger for a while, was running low. I didn't feel like dragging a couple hundred feet of extension cord out, and I just bought this new toy, so I took it out and I'll be dogged if it didn't slice right through the 2x10s I've got! Very well done, and quiet! It was weird.
New tool again! I got an inexpensive Craftsman angle grinder. My last one was a HF cheapo, and it's ergonomics left a bit to be desired. I've yet to use it but it seems like, with a trigger trigger instead of switch, I think I'll like that a bunch more. I also got a grinding wheel rather than using a cutoff wheel to grind. I don't think I realized there was a difference, but that makes sense, duh.
