Heng's vortex 12"
Pulled the trigger on a 12" retrofit fan, the Heng's Vortex III for my kitchen skylight. I've had the 9" vortex II in the bathroom for a few years now and it's proven reliable. $70 shipped, compare...

Well poop. The Vortex is here already, but I don't see how it is a retrofit as advertised: install without breaking the roof seal.
The last vortex came in a frame that replaced the inside portion of the roof vent, and attached to the cross member that contains the skylight mechanism.
This is all one unit, complete with roof flange and everything.
Not terrible I guess, just means I'll have to figure out how I'm going to replace the existing vent in the middle of my non walkable roof... I could barely reach the sides to install the vent cover.
Wow, glad I didn't go with the 3 then! I was considering it for the larger size, more air with fewer rpms should be quieter, but I couldn't find anyone with one in stock for fast shipping so I ended up with a single speed 2 and bought a similar speed controller with reversing switch to turn it into a $200 fan =)
