Engine Stands?

I don't know how much you are going to use a engine stand but I don't use one much at all. When I rebuilt the engine in my car I bought the cheapest stand I could find (3 leg). These stand are bad about sagging. However I cut a 2" x 4" and place it between the engine water pump area and the floor. This kept it from sagging. I would work on the engine and after calling it a night I would install the board. I didn't need a expensive engine stand.
