Not too expensive.
You can pick up Poser 5.0 for around £300 on Amazon. (EDIT: ~£176.0 0 download or ~ £196 boxed, direct from Curious Labs)
Good range of 3d & rended export options.

Perhaps older versions of Poser might still do everything you need and might still be available in some bargain basements or on ebay.
