Good info

If amazon.uk don't have them then these USB dongles are available to the UK through dealextreme.com as well. With the dollar to sterling rates being the way they are today, you're in for a bargain!

Charging dongles are available in Poundland (at least, in the Croydon Pundland they are!) They do a number of them with a retractable USB charger cable, VERY good value for money.
