anybody know about 2-post hoists?

There are a number of things that need to be checked. Cylinders don't fail commonly, but You don't want to be dealing with the mess of any seeping, and having to keep an
eye on the fluid level...so that's 1st. The balance cables fatigue & the bearings on the sheaves for them wear out, those are next. You don't want to be tempted by an older
lift by low $$$ because of the lack of modern safety features. Chief among them are auto engaging/dual-full releasing locks, and spring-loaded arm locks that prevent the
arms from moving/kicking out. Trust Me, they matter. Generally, the condition of the unit overall will tell You if it's been taken care of, ten years is pretty young for a quality
lift. But it is also when a lot of maintenance would be due if nothing has been done to it. It is a top notch lift so, if local prices are high, then that's about right.
