It is so difficult trying to find breeders in this area, I had the same problem as you Jamie
I ended up having to go to a pet shop to get another hammy, it was easier for me especially with my youngest son wanting another hammy and he didn't want to wait
I don't mind travelling up to an hour or two to go to a show, so maybe one day I will venture to one
I travel that much to get to some guinea pig shows and it is always worth it
The London is definately the place to go, there is so much to see and do and you'll be guaranteed a great day out
