Hi Frank,
I was looking into a 12K unit for someone we met earlier this week. I've touched base with the guy we got ours from and he mentioned late today, that he has located one in a warehouse at a discounted rate for them if they are interested.
He may have smaller units, depending on what size you're looking for. If we can exchange contact information, I can put you in touch with him to see if he can help you with this.
As for measurements, I put this in back in 2003, so I'll need to dig that information up. Ours is a standard Marine Air, 12K. Cool only, but I believe the footprint is the same on all the 12-16K units. If you visit the Marine Air website, they would also have this information online.
I don't have an anchor yet, so we can't use the PM feature here, but my email is shadow7118... and I'm on AOL - if you can figure out the rest.
Regards,
