I personally haven't had any problems with it. Now that it has vegetation, I think that it was very worth it. Of course, I got it for $99 at CompUSA. And I'm not sure what it is, but the renders are a little different now. Much better. I could never quite get that photoreal look before. Now I think that I can, and with a lot less work. Plus throw in the soft shadows, color gradients on the lights, some very nice new volumetric presets (which I have been abusing lately, lol!), the new render settings (DOF, blurred reflections, the ability to choose the number of rays per pixel, etc., etc.), and so much more. I think it was waaaaaay worth it! If you get it I don't think that you will be disappointed. ;-)
