You could try Bryce, SoftImage XSI, Wings3d, Seamless3d but, no matter the tool you choose, you are going to have to work through learning it. There is no such thing as a 3d modelling tool that you just immediately know how to use. Also, while free, some of these tools licenses don't allow you to create commercial content unless you pay.
I started 3d modelling using 3dS Max. It is an amazing tool but, as mentioned, too expensive. I tried Blender and XSI and finally settled on Blender because it has the most features and a completely permissible license. It can be hard to learn but, so are every one of these other tools.
