I recently got a T5010, and thus far love it! It's everything I was hoping it would be, but think that a little extra battery power might be a nice thing (running Photoshop and the like really eats power). Anybody have any suggestions on where to purchase it? I've done the Google search, and have found as low as $85 (for a like-new one... but it disappeared from eBay before I got a chance to get it), and new ones around $130. Anybody know of any good battery sales sites?
