2x the price wasn't interesting. Kinda like the Sawstop vs. Unisaur. ;-)

I was really only looking at 8" jointers. I had a Crapsman 6" (from the early '80s) that was in tough shape. I gave it to a friend who has it almost completely restored. It may have been a 6" but it was way underpowered and too short to be all that useful.
It came down to the Jet and Laguna, with cost being the only advantage of the Jet. SWMBO told me to go for it (and gave me the money for our anniversary). OK, works for me.
