The price for the upgrade is a bit high but not much higher than any software upgrade in this price range. The new features sound terrific and I have seen some amazing images done with bryce by the beta testers and those newer users who already have it. I think it has allot of great sounding new features and I upgraded. The reviews I read were also excellent. I like Bryce and I cant wait for the new version. The gallery at bryce5.net has some good examples of what it can do if anyone is interested. I visited all the beta testers galleries I could find and read reviews before making my decision and even personally asked a few beta testers, both of which gave it excellent reviews as well.
