You shoudl be able to get the stuff from Madvapes shipped to the UK. For under $20 (be what, under 15 quid) you can get the parts to make a puck. Uses rechargeable AA batteries....
.... Would have to as a friend of mine but think batteries and cameras and all that are about the same on your side of the pond (electrical plugs, DVDs, and such are different). It's a good little box mod for cheap. Best thing is (for me) is that I already have 12 AA rechargeable batteries for my camera. So worse comes to worse I can always have charge anough to wait for one of my eGos to charge up.
Just thought I would mention it. Figure it's always good to have a spare rig around too
