This sort of thing always comes down to personal preference based on trying out the demos and deciding what's affordable. Maxon's Cinema4D v9 base cost is competitive but for higher quality renders and/or other features then these come in the form of modules which can really push the price up. I use the older C4D v8.5 and find it to be excellent. Poser imports (including animated ones) are fairly easy once you get more used to C4D. Good luck with whatever you decide on.
