i've purchased 3 Sony PHD-A55 Cyberframes from ebay and i think they are the best frames. you have to use memory sticks but those are cheap nowadays. i think they have the best active LCD screen, and i think they are the best aesthetically. i keep one at home and one at work. everyone who sees it at my desk is always amazed by it.
here is a pic of it sitting at my work desk

and here is a pic of it upclose

the one i have at home is teal in color. the reason i had to resort to ebay is because they are sold out everywhere.
