I have to go along with Teyon, Try out the demo's first. Even the software houses have to admit that  a given interface isn't universally popular, ( unless someone comes up with one that reads your mind ), and there are as many as there are app's.  If you're looking for economical, Blender is free, and very good... it does do it all... and a few things that surprise people. If you just want to get a handle on it all, but want to start slow, I'd suggest Anim8or... no, the "8" belongs in there. Lou.
