I just got one through Amazon that is 1000 pounds, it is height adjustable, just not quickly. It has several holes up and down the legs, and you set it where you want it. I figured it made a very sturdy bench like structure. My plan is to build it out with a box underneath so I can put in storage, drawers, like a cabinet, but without a need to frame it, thats already done. It was 139 bux, and they had them from 99 up to 300 or so with a lot of different perks. Mine is electrified, and had both flat feet, and rollers to put into the legs. I'm thinking stored along a wall, and rolled out as need mostly for working on, but assemblies more than anything. Came with a 1 1/2" solid wood top. Cost wise at first it sounded high, but with plywood 50 bux or more for XYZ stuff, much less cab grade it started to look like a deal.
