How much do you use your tablet? I use mine so much that i just got an ipad 4. The resell on an ipad 2 is awesome. You can still get $250. The main thing to watch is how long the 2 will be supported. I have a feeling after this year, software updates will stop working on the 2.
The ipad4 is the best tablet out right now imo. Sell some sticks and try up your budget for a 499 version and you will be set.
