Cinema is not what I would call cheap but it does seem to be lower than the others in its class. Also it can come modular so you can just get what you need (for me that's the core and the Advanced render module). Still runs about $10x bryce though for even that. I love C4D but I still have a spot for bryce in my apps.

Pass no temptation lightly by, for one never knows when it may pass again!
