DAMN!!! $1000, I don't know who's selling it, but they are losing money. AutoCAD runs US$3,295. It is really not a good program at all for 3D work, but for drafting, it's hard to beat. As for Solidworks, it's a quality program, I've got nothing bad to say about it even though it is one of my biggest competitors. Inventor is another nice 3D modeler. Real similar to Solidworks. About the only MAJOR difference is who makes the two. Back in the day, there was one decent drafting package and one or two modelers. Times have changed and it can be hard as hell to tell two different modelers apart anymore.
As for AutoCAD vs. Solidworks or the ease of use issue... AutoCAD is bone simple to run, same with most any CAD package, it's just like anything else, the deeper you get into it the tougher it gets.
