i think if u read a few pages of maxwell, you will love it, cause it really doesn't takes to much to render... you can render a nice sun study in one image render....and it has some great stuff for ligthing that when you render a single image you can adjust it teh way you like after it renders and all in real time. and time, if you have one hour, or less, to present some 3d sun study or whatever, it will do it @ the time you say so... and the image will look much better than other 3d renderers.....
so just read few pages and click on it, i made my boss buy it, but he doesn't use it, but i use it at home with a smile on my face, and some nice images too.... so don't doubt about it, get for you... and its getting stronger in each update
