Wilson Audio floor jack

Has anyone found a suitable or similar floor jack as the one Wilson Audio dealers have ? It is used to prop up the MAXX or Alexandria when changing the wheels to spikes.
The jack has to have a very low minimum height.
I just went and bought my dealers "demo" Wilson Audio floor jack.
A beautiful piece of machinery. I plan to change the wheels to spikes tonight.
How much is it ?
I answered your question in an email.

BTW - for those interested, RRP on the brand new jack is $799.
Is that the cyroed model E?
Actually, my Wilson dealer says the floor jack costs $799
Wow. Un--believable. I mean the jack is built like piece of jewelry, but $800 !?!?!?
