Silo 3D actually gets an update
I know I'm not the only fan of Silo 3D here (although I wouldn't recommend anyone purchase it given their lack of updates and terrible communications) but it has actually been updated (mostly bug-fixes, a Linux version, and 64-bit support).
These days, I hardly use it at all. IMO Cheetah 3D has actually surpassed it as a modeler for most purposes (thanks to non-destructive modifiers and scriptability for starters), but one place where it simply rocks is producing clean booleans.
