[Elecraft] K2 Power Supply

I used a K2 for about a year on a 25 amp Radio Shack Switching Power 
Supply. I am now using the same supply on an ICOM 910H. There is an 
enormous to-and-fro on this reflector about the merits/difficulties of 
switching supplies which I do not want to breathe back into existence, 
but I have never had any problems with this set-up or with the Pyramid 
switcher I use on my K3. These power supplies are small and very 
convenient. I use a brutish Astron 70 for my TE Systems amps...it keeps 
the shack from sailing away in a high wind.

As I move closer to the testing stage (probably another month or so) I am starting to think about how the unit is powered.  I am guessing that there is not an internal power supply.  I also did not order the battery option.  What suggestions are out there for powering the K2?  By the way, I do have the 100 watt option, in case that plays a role in choosing a power supply.
