Quote:What NOT to look for in a CAS calculator
The primary use of your CAS will be for use in SACs, tests and exams. Buy a CAS based on its functions to help with your success in these SACs, tests and exams, not for the following:
• Whether or not it can play games
• Whether or not it can store images
• Whether or not it is in colour
• Slight cost differences between models
• Whether or not it is new
• Whether or not it is aesthetically pleasing (colour, shape, weight, etc.)
• Whether or not it is touch-screen/touch-pad/click-pad/etc.
• How many batteries it needs, and of what type they are
Quote:Recommended CAS’s by VN (based on the above information and not in any particular order)
• Casio ClassPad 330*
• TI-89
• TI-89 (Titanium)
• TI-nspire CAS
• TI-nspire CAS with Touchpad
• TI-nspire CX CAS
*Known to crash during VCAA exams

Ok, can I start laughing now?
Besides not including the 50g and the Prime, whose CASs are quite capable... ouch, Classpad 330 ?!
Even suggesting its newer sibling the fx-CP400 II would be fairly bad advice (the calculator is severely overpriced for its limited power, openness and versatility), but recommending that older-gen model is wrong.
