I was more reacting to your comment below.
“I do not think it is fair for the minority who have the time, equipment, and skills to demand premium prices for their work, unless they had to invest several months and a lot of money into the model.”
I don’t mean to sound greedy. To anyone who has the free time and space to share and help grow the community, you are to be commended for it.
But please don’t be critical of people looking to make a business out of it . Sometimes there really is another side of a business not well understood by many. Software is getting expensive and a lot of capable free products (like sketchup) are no longer free and cost money for commercial use. Plus as I mentioned before, posting items for free or at a substantial reduced cost has a risk of being reposted or sold illegally.
