You can also use Anim8or, but from what I've seen of Geep's tutorial for Wings, either one will lead you down basically the same path(nothing wrong with that, please don't take offense Dr. :) ). What's lacking though I think is a tool that will let you extrude body parts without having to move each vertex or edge individually. eg: if there was a way of "pulling" out one joint and defining an area around it that would stretch out with it so you can get smoother deformations without many hours' work.
