I bought the Pro version on July 31st because the deal was too good to pass up:

$750 for Pro version (normally $1500)
first year maintenance free (normally $350)
training DVD (worth $300)
12-months financing at 0% interest
bundled with Hypershot Web and advanced 3D PDF exporter

But i had only 3 or 4 hours to try it before I bought. Alibre has a 30-day return policy. So i have decided already to return it because, like you mentioned it is sufficient tool for part engineering but not so much for product design. It can not really produce any blended surface shapes other than lofting. Can not do any fillet except for rolling ball. And the Rhino plugin isn't much more than using standard Rhino block objects. That's why i am returning. Although i realize it's the best deal i saw from Alibre in several years... But then i thought, i will return and just buy the $99 deal. But they said anybody who purchased in July can not purchase the current $99 offer! So now i plan to return it and wipe my hands clean... :)

Also the $99 offer is not refundable. You buy it, you keep it!!!
