Mr or Ms Bento

Does anyone have any ideas on how to get a Mr or MS Bento (Or similar item such as the Thermos Nissan?) in the UK without costing an arm and a leg? I have tried with no success to track one down. I'd really appreciate ant hints or tips on getting this. I'm not interested in joining Ebay and Paypal solely to get this item as I've been a member previously and been stung :0( Thanks in advance for any help!
