I've been with Bryce since its inception into the PC market, even followed it around when it was strickly Mac, a $100 update, in my opinion, for a more stable, more robust Bryce, faster with a few extra added goodies is a fair deal to me. A $300 update, well, isn't a version update, it's a whole new middle market program release, and although I very much enjoy Bryce, I would have to think twice about paying that kind of money for an update, especially if the program is earmarked with bugs.
