TrueSpace provides a lot of functionality for the price. The new TrueSpace 6.5 is priced at $595, but even TrueSpace 5.2 at $395 is a very powerful package and there are lots of add-ons and stuff available. If you download the demo, the Caligari marketing machine starts and you are immediately offered a reduced price and/or some CD's with add-on products for free if you order within 30 days. So I would think that you will end up close to $500 even for TrueSpace 6.5. It's not available for Mac OS, but there are add-ons that allows import of Poser pz3-files into TrueSpace. A bundle with Poser-Vue-Mover-TrueSpace sounds like an extremely powerful combination with a great workflow based on pz3 format.
