I like Alibre and they have a new version due out early 2013 which will let you use one Sketch to generate more than one extrusion, you can even fragment it. Their current one Sketch per is a pain.

I got the "Standard" version for $99, which was dumped and my licence grouped in with "PE". Hassle is PE only comes in 32 bit whereas Standard came in 64.

I liked their sketch, constrain, dimension approach so I had to fork out for a "Pro" 64 bit upgrade. They told me to me buy the cheaper Standard service contract at the same time as I got the upgrade so I saved a few quid, I got it in writing that I will get the new Pro version when it comes out on the strength of that.
