Should i get a blackjack 2, pantech duo, or the new version of the razr?

ok, my palm centro broke about three times and my family and i are pissed off at att and t for my phone for not working three times already. We talked to the customer service and they said i could switch my phone for a blackjack 2, pantech duo, or the motorola 2. I want one that is good for a 15 year old teenager. And i want a fone that wont break on me. thanks
