Blender, the most awesome modeller when you learn how to use it
http://blender.org has a ton of good tutorials on their website, plus if you goole some websites you will find tutorials
I am getting quite far in blender too
also i have tried many other modellers and came back to blender for these reasons.
1) the interface is brilliant
2) there are hotkeys as well as buttons
3) buttons are arranged nicely and sorted into categories
4) it is powerful!
5) very easy to use once you follow a few tutorials
and theres more that i forgot
im not saying anim8or isn't good but i tried it and hated it, not a vary nice modeller to me. By the way i did spend alot of time in these other modellers i tried that were recommended, but for some reason after all those hours i still didn't even partly enjoy it compared to blender
but its up to you, pick what you want but i recommend blender.
