I'm buying one of these two: http://www.amazon.com/3DS-Zelda-Armor-Gree...2878&sr=8-4 (Crystal Armor) Or http://www.amazon.com/Power-Pak-Nintendo-3...2859&sr=8-2 (Power Pak+) I really like the Crystal Armor look, but the Power Pak+ increases the gameplay time. And if I ever have to send my 3DS in, I need to uninstall it from the DS before sending it in. -.- AND the Power Pak+ also has an almost $6 s&h cost. That's horrible. Which do you think is a better deal?
