Well, I ended up ordering this:
http://www.directlift.com/Pro-9F-Two...ift-P43C8.aspx
There is a Direct Lift warehouse less than 3 hours away and shipping was $230. I compared shipping weights of the 9k lifts and the 8k lifts with the 9's being significantly heavier and probably overbuilt for what I will be lifting. I spoke with warehouses in 2 different states and everybody was prompt, knowledgeable, and nice! Direct Lift is owned by Dover...who also owns Rotary and Revolution I think. My footings should be nice and cured by now...hope the install goes smoothly!
