blackjack battery life

What should I choose? Good choice, but some opinions!?
I debate with the cell phone you will receive. Decisions are have been reduced to the Samsung Sync-$ 50-Heard it's ok phone, nothing works very well. Black Motorola Razr V3-$ 50-Heard this phone is not very well, and is best feature is the eye-free Sony Ericsson W300i heard the biggest problem here are the buttons from Samsung, but good overall Blackjack-Refurbished-$ 70-Heard-battery life sucks, and buttons are tight. Samsung SGH-A727-$ 100-Heard its ok, but the keyboard is slippery and can not hear. Moto RAZR V3x-$ 100-heard it's better than v3, but it is particularly bad. Cingular nobody else wants to give its 411 on these phones? All have one of these phones, and we do not consider it a good offer and is a good phone. Any exp staff. would be great, or what you've heard. Or other suggestions would be great on some phones. So what do you think? ! Thank you.
Sony erricson my friend and really had loved, and regrets get a new one. My dad has a Samsung and she hates it.
