Cutting tool/blade prices are dropping rapidly.
I bought the Porter Cable version, and fried both of the batteries in 3 days of hard use (installing wood floors) Nice tool, reasonable price and were I looking for a corded version, I would get the PC.
So, I returned the PC...bought an 18V Li Makita. Great tool, lots of power, good batteries, but frankly, heavy.
This kind of tool is incredibly useful...my uses have included cutting individual boards out of old wood floor (to feather in new), flush cutting trim, plunge cutting holes in plywood and floors, and plunge cutting long lengths of subfloor...
Your call on corded vs. cordless, I would get the Makita for cordless, but the PC was a thoughtfully made, reasonably priced tool undone by poor batteries and I would chose it in a corded version.
