Hope I'm not too late to add my two cents. A month ago I faced the same dilema, zorares. I'd used B4 for a year and was unsure whether to upgrade to 5 or "sidegrade" to Vue 4 (B4 users can get Vue 4 for $169). But I, too, was worried about learning a new program. After seeing what the Bryce 5 upgrade offered over Bryce 4, I decided to go with Vue. And, man am I glad I did! It's a fantastic program and there was almost no learning curve. I'm not going to waste space here spouting Vue's virtues, just take a stroll through the Vue forum. Look for a thread titled "Why do you like vue over bryce," (or something like that). It was posted last week and it will explain everything.
