The Blender-AvaStar combination is still the least expensive entry point for making clothes, animations, and avatars for Second Life™. Blender is free and awesome, if difficult to learn. AvaStar has sold for US$27 for, I think, a couple of years. So, a price increase is to be expected.

At the end of March 2017, the price of AvaStar will increase from US$27 to $40 for the full version and yearly support from $14 to $20. So, if you have been on the fence about purchasing AvaStar, now would be a good time. I plan to update my support package. See: AvaStar Pricing.
