I have gone the reconditioned route a few times, and every time I ended up throwing the stupid thing out. It just never worked right. Now granted the last time it was one of those Black and Decker jig saws, and the only way I would work is if I mounted the blade in the machine backwards. Even then it lasted like a dozen times then the motor crapped out.
Now I just buy new, and buy professional quality and I'm much happier.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
