I had my eye on the corded 12 amp Milwaukee, but tonight I learned my brother in law has a Sawzall I can borrow. Since my only immediate need was to cut a hole in the wall for a doggie door, cut another hole in the wall for a stove vent, and remove a couple of soffits in the kitchen, I'll just buy some good blades and use his. I'll save the money for something else. Like a wood stove in the shop.
I had an 18v Ryobi cordless saw that was OK for what I originally purchased it for (removing old rain gutters), but the batteries didn't hold much of a charge and they completely died within about a year. If I ever do buy another recip saw, I'll most likely be buying a corded one.
