I know the CompUSA up where I used to live in Michigan used to carry RDS4 and 5 a few years back, Thats where I initially bought it. But that was back in the Metacreations hayday. Personally Maya and 3Ds may be powerful but I haven't foudn anything I have not been able to do it RDS or Carrara, and I like the interface a lot better than Maya or 3DS or Lightwave. I do like the free floating camera system in Carrara, I find it confusing working with three open windows or more most of the time like most folks do in the higher end software. And personally I dont think there is any excuse for charging what they do for those packages.
