Thanks for all the comments. I have seen used lifts come on the market now and then--most are 2 post from shops that are relocating or shutting down. I think the two post lifts need just a little more space on the sides--my space is limited, thats why I think I want a four post model. I'll post an update if and when I decide on something.

Thanks again for the comments.
