I know you're in Cornwall and not Devon but - the Southern Hamster Club have a show in Dawlish (Devon) on 30th March and there will be hamsters for sale there from breeders - so you would get a healthy one and probably with a pedigree. It could also be something to look forward to. Although I know Cornwall is a big place and it's a long way to Dawlish! But it might make it special. You'd just need a good pet carrier for the journey back
Details here - breeders will be showing hamsters for judging which is why the categories are listed, but also selling some.
