so stick with the free version right?
Definitely when you start. And from what I've read on here the only advantages of the Pro version are Layout (which no one seems to use anyway because it's too buggy) and exporters for 3ds and obj. If you absolutely need these exporters then you need Pro, but if you don't need them then the free version will be fine for you.
As far as I know the Pro version doesn't offer any extra modeling capability. I have the free version and haven't even tried the pro trial, so a Pro user would need to confirm that.
