Hi
I totally agree with Marco. If you like MoI, buy it now. Betas have always worked for me though you have the option of using MoI 3 until the MoI 4 is released and beyond. Don't wait for 6 months to a year until the next version is released.
cheers,

OK, OK .. you guys talked me into it. Time to pull the trigger. :o), Thanks everyone for chiming in. I have experience with Rhino3d from years ago, then I got caught up in SubD polygonal modeling (Modo/Lightwave and the LWCad plugin). So what's the upgrade pricing looking like from V3 to V4 ... down the road?

Hi Gary, I hope it will be useful for you! Upgrades from a previous version to the current one are $100.
