As far as bundles go, there are usually deals to watch out for.
The other thread has a link to the Sony Mediasoftware shop that shows a price for the main package. Oasis is sold through dealers and other developers such as vtworx.com and videohardware.com .
However Mirage Lite might suggest something else. Perhaps a different application altogether. However the justification for Mirage relies on more than the use of LiveType. You need to be intending to immerse yourself in everything else paint, FX or print that might result from owning it. IMHO.
