Last time I checked, the full version of Bryce (v5) was $80. Version 4 was being given away for free in at least one computer magazine in December. I'll have to point you to the 3D Forum for the name of the magazine though, that's where the thread was posted. You can read more about Bryce at http://www.daz3d.com, they bought it from Corel last year. If you're in the USA, Bryce is usually on the shelves at CompUSA, that's where I bought my copy.
I second CattleRustler's opinion that Advanced Terrain is the way to go for outdoors, and I also feel your pain on the registration issue. It's been one of the few problems I've had with the AT plugin and I hope to solve it one day because the Bryce .X terrain export includes a heightmap that works really well with the plugin. (I don't get any $$$ for mentioning Bryce repeatedly, I just think it's a wonderful and underrated tool that works well with DBPro)
