I've got a Universal Auto/Air Power Adapter from Targus. These puppies cost about $86, but it's powered every laptop I've ever tried on it (Dell, Toshiba, Compaq, Fujitsu, IBM) including the one that functioned as my in-car mp3 player before I got my empeg. I now keep it in my empeg carrying case and take my empeg with me when I travel with friends or on a flight. I also keep both a tape adapter and a FM transmitter in there, as well as an assortment of adapters to go to 1/8th male or female and RCA male or female. That way, if I get to a party, I'm always ready to whip out my empeg and provide tunage for the masses. The tape adapter isn't bad if you get a decent quality adapter. The FM transmitters plain out suck and should only be used as a last alternative.
