"fast framer" shed construction system??
 

I'm debating whether or not to build a small 8x8 garden shed when I came
across "fast framers" that supposedly take all the guesswork out of angle
and other cuts. For me, this might be ideal as I am not exactly proficient
in DIY tasks. Does anyone have experience with the fast framer system? How
is the durability/ corrosion/ rust resistance?

Thanks,
Al
