i use 3DS Max myself,
used to sketchup, but far too limited.
edit:
what game are you working on anyway?
im working on an extensive game myself, and im looking for
more modelers and programmers, as we are very spread out over just 2 people, and a few helpers.
i was sort of hoping you could perhaps help us out...

A chair looks like made from plasticine..
