VAC Ovens

Ok guys I am going to get one, just trying to figure out what one.
I am looking at the Across International ones, the .9 and the 1.9.

what i want to know is:
who has what?
what pumps are you using and sizes?
how long does it take to get full vac?
if you have one of one brand would you go back and get a different one/if you got the .9 do you wish you got the 1.9?
do you wish you had more shelves or finding that your not using all the shelves?

i am looking to buy it monday, the guy from A.I. is sending me some quotes but he saying the 1.9 needs a 7.2 cfm to work right and that is a 690.00 up grade, but he recommends the 9.5 dual stage for best results and that is a 1500 dollar upgarde.

i have a dual stage 3cfm pump, is it just a matter of time?
thoughts opinions please

i hear its handy to be able to adjust the temp of each rack

I have not see that feature, all the ones i have seen work like a convection oven

How do you convect in a vacuum?

they appear to have holes in the back inside the chambers, i assumed there was a fan, and i understand where your going in a vacuum there is no air to move around. that is why I am asking questions... do you have one Snaps?

I've worked with AI's and Binder VDL's up to 4 cuft. It is my understanding that the oven chamber surfaces emit and reflect infrared heat generated by heating the other side of the chamber. Never had one apart.
