too bloody expensive and around 1/4 of the features of Softimage...
athough it is an all-in-one studio, personally i find how its setup is just awekard as hell (and this is comming from a Maya/Softimage user!)
i'd suggest grabbing yourself SoftimageXSI Exp from thier website instead, especially as almost every major release over the next year for the PC will be using it.
HL2 would be one of the main ones... so just like people wanted to to make models for UT2K3 they grabbed MayaPLE you'll want XSI-Exp for the new wave
my advice about Houdini is avoid it like the plague unless you have a job that needs it
