Three words; hydraulic lift table. I put off buying one despite others claims to their usefulness. The last Horror Fright sale plus coupon made it about $200 for the 1000 lb version and I bit. True, you have to store it when not in use. Like pipe clamps it can be awkward to store. However, just like those pipe clamps, when you need it and its there. . . the storage issue fades quickly.
I have seen people trick them out with work surfaces but, I feel it is a little unstable for that. I don't think it is going to fall over or anything. It just has too much wiggle to be a work surface for me. I just use it to move things up and down. Humping one end of something onto the lifting table, swinging the other end up and pumping with your foot beats musceling heftier weights up onto and off of things. Christmas is coming . . . . just sayin'.
