I know that they are expensive. Leave that aside for one moment. I'm interested in finding out about them because even the most ardent hoisters say that they can be safely operated by one person, as opposed to any other type of hoist. I hate the fact that I can do very little in the way of moving and handling on my own now (I could probably do it, but the repeated cautions have got to me and I'd feel really bad if either of us came to any harm). I'm interested in hearing from anyone with experience of them. Thanks.
