I've found Bryce to be a useful app. It's not as robust as some but yields nice effects with little effort. The render engine in 5.0 is pokey but it's affordable. Now with the promise of 5.5, I have just been informed by Eovia that there is no upgrade pricing and 5.5 is full retail. I bought Bryce. I paid to upgrade to 5.0 and now all of that counts for zip. I'm at square one. Bad move.
