I bought 6.0 today. I have never used Bryce before. But I downloaded 5.5 and then upgraded to 6.0. When you do they offer you a free interactive tutorial and give you a 30% off coupon for any additional purchases. I poked around and found a bunch of stuff already 50% off, and tried the 30% off coupon and it worked. So I sent $60 and left there with version 6 and about $200 of add-ons. I guess I now need to learn how to use it all. :-)
