I searched around; there doesn't seem to be a bunch of options available right now. Have you seen TonyT's thread here? http://www.dtvusaforum.com/everythin...-standard.html I'm not sure how the cell phone industry is tackling the battery life issue when TV phones hit the market in full swing, but as of right now, all of the handheld ATSC TVs at Amazon.com (as you mentioned) are rechargeable, and last only 1.5-2.5 hours after a charge. Purchasing a second Li-ion battery might be an option for you, but not very cost effective.
