I've got a (very) rough & ready Titan el cheapo recip saw which I only really use as a tool of mass destruction.
I'm increasingly having to cut half laps in 3 x 3 posts and doing it by hand gives accurate results - but is bloody hard work.
Tried my Makita jigsaw with extra long blade, but even on a tool of that quality the blade wanders.
So, I'm thinking of laying out for a quality (Makita/Bosch) recip saw & the right blades.
Anyone got any experience of a good quality machine? Is it possible to get accurate cuts?
