Hi,
I get all my stuff from Expansys, next day delivery if the item is in stock.

As for powering the XDAII I'm going for this ...

But only because my GPS is in the boot and powered seperately, otherwise I would get a combined GPS / XDA charger.
Something like this ....

(which has a holder too, if you havent got one - but check if it's XDA 1 or 2)
However I do prefer the compactness of the magnetic holder
