Oh please, Michael! Take the UN*X approach and leave printing to other better products.
MoI scores so highly because you ONLY focus on the 3D creation side of things!
This tool is by far the easiest I've ever used. I just spent 4 weeks creating a concept design in Sketchup v7 that I was able to recreate in MoI in 4 hours!!!
And with MoI's perfect .STL output, our Dimension 3D printer sees no errors.
Try that with SketchUp!
just keep in mind, the annual maintainence charge for Alibre Standard is about $300. They have a new version coming in September. You won't receive tech support or updates/upgrades unless you pony up the $300 first... I believe they have a deal right now for $348 which includes the first year of maintenance charges...
