I know TRIsoft sell's EA-70S for about EUR50 and I know people here use PSP AC adapters. And I assume any good regulated 5V supply would do, but I do want something as cool as the 100V adapter (EA-72) that ships with Zaurii. I've never seen an AC adapter that small (and it does 1A DC output).
USB power is not really a solution as I have an SL-C860 which doesn't have a standard USB socket and don't want to carry two cables (Zaurus-USB and USB-AC).
For sure, I don't want to burn my Zaurus. So something tested with, approved for Z is worth a few EUR more.
