Thanks for the clarification. That is, IMO, a replacement for a chainsaw rather than a reciprocating saw. It is the price of an expensive chainsaw and three times the price of a modest reciprocating saw.
Also, when cutting 300mm diameter wood isn't it rather a sledgehammer to crack a nut?
Good point about the cost, however the black and decker version is £42
