You can usually get a copy of the mag at B&N, or Borders for about $15bucks. I believe there is an upgrade offer in there. There has been a vast amt of improvement in Carrara, but I don't know where you can see a list. It depends on what you want to do, as to whether it is worth the energy. Carrara will be available shortly at DAZ, I am sure for standard they will have a good price so that is an option too. You can get 3 very cheap then upgrade to standard inexpensively. I am sure there are bound to be some good prices coming tho.

No need to think outside the box....
