I couldn't agree more... and for the price, it couldn't hurt to use it. I mean, it can import so many different formats and even export more.
Check out their
archives page and just look at some of the images.
I found the image below after doing a quick search, over at

Bear in mind, that for whatever reason, this guy posted this image as a test, because it was rendered using OSA 8!! It was also rendered using Blenders internal render engine. You can easily export your rendering jobs to Yafray, Virtualight, POVray, MegaPOV, Lightflow, Radiance... and a few others.
