Think 3 any good?

I am looking for a new CAD program. My background is Rhino and ProE. I have been looking for one program that mixes these two programs together and just finished an online demo with Think 3. It seems to let you play with surfaces quiet well (like Rhino) but has parametric abilities (like ProE). I don’t care about rendering as I can do that in other programs (like Eovia). And it costs $4,500 a year (which is in my budget)

Has anyone actually used Think 3 and what are your thoughts?
