No question in my opinion, Wings3d is free and one of the best modellers available. It doesn't have a renderer (though free ones are available) but if you're modelling for Poser you already have one! You'll need to be running OS10.2 to use the latest version (the older ones won't import poser figures)but it's worth upgrading if you're on 10.1 I can't tell you how great this app is, you've GOT to try it before you splash out on Lightwave or similar commercial app. Baz
