I'm with you!  So far I just love Silo.  At $109 it's unbeatable.  It's soooo much more intuitive than 3DSMax, and I've hardly even touched the tutorials.

The questions are - how fast can I get out of the starting gates with it, and will I start to feel bogged down by its lack of an all inclusuve set of features (i.e. export here, import there, repeat ad infinitum) in 6 months?
