We've been trying out some different types of concrete saws for cutting foundations for egress windows. If that's all we did, I'd probably go for a ring saw, but I can't justify the cost. For a dozen or so egress windows a year plus miscellaneous use, it seems the cut'n'break would be the best value. There are two Husqvarna models I'm looking at -- the electric K 4000 and the gas K 760. Does anyone have experience running both? We've had issues with fumes in the past so I'd really like to use the electric, but the specs are 5 HP for the gas vs 2.4 HP for the electric. Should I expect to cut significantly slower with the electric saw? Not sure how the numbers apply in real life...
