I've been using the ProgeCAD free version of intellicad for a while now, and I'm looking to upgrade it to one of the other versions. I'm leaning toward either ProgeCAD, the Autodsys version, or the Cadopia version. But there's maybe a dozen or so other vendors as well.
Does anyone have an opinion on one version versus another? Are they all close enough that a person should just go by price alone?
