I've ordered this one from Fasttech in Singapore -

Trackable mailing is included in the price and the PayPal conversion came out at £16.32, which keeps it below the £18 limit for customs.
Don't explore the website, it will cost you money, especially the LED torches (I ordered 4 x 450 lumen Cree zoom torches for £15.92 as well).
The only negative is the time from order to delivery, I'm still waiting after 3 weeks although tracking shows that it's now in the UK.
