blender is nice... it takes a little getting used to... but so does any other 3d modeller/renderer. you cant really go wrong, cause its free. If you don't like it, its not like you just blew hundreds of $$$ on max or something.
I've "unofficially evaluated" bryce and max and truespace and some others, but kept finding myself coming back to the free tools like povray and blender...
its not explicitly a home modeller, but can be used for just about anything... check out the blender resources on the web and see what I mean. Some pretty amazing things are being done with it... incredible still shots and mind blowing animations.
I used a couple tricks to make this look nice... I used the toon shader to make the lines pop out and misused radiosity to make the walls glow blue and red in proximity to the mic and speakers (but that was an accident).
anyway, here's a link:
ooooh... 2.32 is out!
give it a try... have fun.
btw... blender is cross platform too...
