Need a bargain wifi tablet for social media

Hi! I need a wifi tablet for a new social media job. I'm on a campus and need to snap pics and post stuff to facebook and twitter. Want a moderate - good camera & good browser. Size of tablet doesn't matter -- I always carry a big bag. Sturdy is a plus -- hoping for 2 good years out of this thing. Bargain will make boss happy, and more likely it'll get approved and I won't have to use my own camera & download to pc anymore.

Anything you know fit the bill well? Thanks in advance.
