Hello everyone. I am new the forums, but not new to Google and Android. I just purchased an NSZ-GT1 from Best Buy as an open box item. They had it marked as $69.99 and i talked them down to $49.99 because it has no ac adapter. 1. Is this a good deal (they had a couple more that I could hook up in the bedroom and son's room)? 2. Where can I find a replacement power adaptor? 19.5V seems to be an odd size. Thank you in advance for any help that you have top offer!
