Bendpak or Rotary are the big names. Bendpak is probably the most expensive, but the quality is good. Rotary is good also, but I prefer the color scheme of the Bendak. There are a lot of cheaper options out there, likely made overseas. I'm sure the quality is fine.. but you know there are only two posts and four arms holding a vehicle weighing thousands of pounds above your head.
I just ordered and received mine from Bendpak. All in, a pretty simple process. I emailed them, they send a quote. Free shipping to your door if you have the ability to unload. If not then you get into fees with the piggy back fork lifts, or lift gates which can be expensive. Another option is to ship to a local freight depot which is free. Then you can pickup from there. That's what I ended up doing. I'm sure Rotary does the same thing. Shipping time was about a week I think? Your mileage may vary depending on your location.
Helpful tip, if you settle on a lift read the concrete specs carefully. I read the concrete specs in the install manual, poured a slab based on those specs. Turns out, there is a supplemental concrete spec guide for Bendpak.. which goes into much greater detail. I missed that, and now I get the opportunity to test my jackhammer skills while pouring a new footing. All lifts are different, so all specs are different. Just be sure you do your due diligence. If not sure, contact the manufacturer. Which is what I should have done.
