I bought one of those cheap china hoists. It a collapsable hoist. The castors they use are absolute crap. When I was assembling it, I dropped one of the legs, it took about a 2 foot drop-and hit right on the castor. The thing EXPLODED. Ball bearings flew everywhere. I went to the local harware store and bought 6 new USA built castors. The bolts it came with seemed wimpy to me, so I replaced them with all USA G8 stuff.

Other than that it has been a good hoist. Moved a bunch of engines with it, never another problem. But it did suck to have to replace castors on a new lift. Good castors are not cheap, I paid $18 a piece for them.
