Hi Chris, for free rendering software, check the message above (http://moi3d.com/forum/index.php?webtag=MOI&msg=788.2).

For commercial software, there just doesn't seem to be very much out there for low cost (say less than $200). The main one that comes to mind is Carrara from http://daz3d.com . There are a lot more choices around the $500 or $700 range.
