Any words of wisdom re: engine hoist?

["Steve Hammatt" <shammatt@sos.net>]

I know we've covered everything about engine stands, etc. but now 
I'm looking at getting a roll-around, fold-upable, standable in the corner 
type engine hoist.  You know the type with the hyd cylinder and hand pump, 
legs that fold up (but still have 4 large casters on the ground), etc. 
I didn't see one in Harbor Freight online.

Any suggestions?
