Anyone Have Stacker Lift(s) in Their Garage?

I have too much **** in my garage! I'm trying to find a way to double stack vehicles (NOT the Tundra! ). I must create some storage space for other equipment and toys I have accumulated. I'm looking at the stacking lifts like the one below, or maybe the versions with four columns at the corners. Came to my TundraBuds first for advice...Got any cheap (be serious) suggestions?

Garage sale.

 

I am selling some small stuff, and using up stored project building materials, but it's not enough.

I essentially need another garage footprint to unwind the chassis and body of a classic car for restoration. HOA won't understand if I sell my riding mower, push mower, chain saws, dump cart, tow behind sprayer and other crap needed to maintain this place.

 

This is beginning to look like the most economical choice: https://www.northerntool.com/shop/tools/product_200466927_200466927
