I agree. Silo is pretty cool. I downloaded the 30 day demo and I gotta say for $109 why wouldn't you buy it? For people who want to learn how to model but don't want to or can't afford to buy a complete package like Maya, Silo is perfect.

The 'tweak' mode is fast.

Don't know if I will purchase it once the 30 days are up, but its cost vs function is staggering.
