Reply to Should I buy a case or bag with my S4?

I want to know if it would be worth it buying a case or bag for the S4, I can't seem to find one that I feel comfortable with, like the weight, the size, the price, etc. I just want to know if it is a good idea to buy like a flight case/coffin or bag for the S4 for when I travel. Since I can't find one that fits me, does anybody got any recommendations?
I would apreciate a link to the website which it was bought and I would perfer US dollars but you can send me it in a different currency.
