Lets not forget Xfrog! If all you need is non-animated trees for importing into Bryce then Xfrog Lite does a great job. It's also a lot cheaper, running around 130 to 150 dollars. Here's a link to an example over on the Xfrog site in case you wanna take a peek. Also, you can buy tree and flower packs, which come in Xfrog format... which means you can open them up pre built, then tweak'em as much as you want.
