Accessories for the Nspire CX

Good morning
I hope I've posted in the right section of the forum, I've got two questions for you:
I've just bought an Nspire CX and I'm carrying it inside a normal pencil case, but I would like to purchase one for my calculator (and possibly for pens, pencil, rubber, ruler...). I saw the HESPLUS case but it's unavailable on the italian Amazon. Do you think that this one is a good product? Do you have better alternatives? What are you using to carry your calculator?
Second question: do calculators need a screen protector? Do they scratch easily? I'm always using the back plate when storing my calculator after use, but reading about scratches on the plastic screen made me doubtful.
Thanks in advance
EDIT: A third question, not related to the title: how do you take animated screenshots like in http://ti-pla.net/a6652 and http://ti-pla.net/a3766 ?
