I doubt you'll find any of these around for a decent price. I looked into getting the components a month or two ago and most of them are discontinued or obsolete parts. Your best bet if you want DC-DC operation is to go to radio shack and buy the car laptop power supply they carry. I bought one for $50 and it has worked great now for about 10, 8 hour plus road trips.
