Foal Farm is a Rescue Centre near Biggin Hill Airport in SE UK. They have a small animal section which takes most rodents etc including Rabbits, Guinea Pigs, etc. I checked a few days ago and they have two Hamsters in, one Syrian (page 5 at the bottom) and a Robo (page 6 at the top).
If your down this way and thinking of getting a new Hammy please check out their website.

PS there was a third black and white Syrian but he/she is reserved (page 6 at the bottom).
