I use several software packages (VUE 5i, Corel Bryce 5, Cinema4d CE+, Carrara Poser 6 and Truespace 5) I have found that there isnt any one perfect package out there try out demos of the various one's out there and see what fits you best. I use Carrara to do alot of my rendering its easy and produces great results however the modeling is weak, cinema4d or truespace has a better work flow. Take a look at carrara 3d basic V2 great package for the price. Hope this helps.
