I'm selling my T3010D and have a second AC Adapter which I leave at work. Beats changing batters. I believe I paid $60 for it. Make me an offer.
Enjoy the convenience of having an extra AC adapter. Put it in your carrying case so that it's always handy; dedicate one to your Port Replicator so it's always there; or keep one at work and one at home.
