Rory_L, don’t forget Lightwave has a smaller learning curve as well. One of the main reasons I went with it myself. Most other apps are like the fully equipped SUV’s which can do many things. I equate Lightwave with my Toyota Camry. It’s got the basics of everything you need and not a lot of extras (except for several third party options), but it will get you to where you want to go. To me, it’s the best bang for your buck (outside of ZBrush of course!)
I haven’t tried Modo yet, but I know if animation is important, it’s not really a stand alone option yet. But it has a great renderer from what I’ve seen. And have heard some good things about its ease of use.
