Which rendering application?

Hi, I have always used Modo to render objects created in MoI by saving files in the .lwo format and then importing them into Modo. However, the current model I am working on is particularly complex and moving it across to Modo throws up a few issues for me so I was wondering what people around here use to render with? I want to get as good a finish as Modo does if I can.

Look forward to your suggestions
