Thanks guys.
I think it's just my area? There is absolutely nothing for about 80 miles (in terms of hamsters for adoption). I don't want to support P@H nor my local pet stores who use large scale breeders. The nearest hamsters for sale other than pet stores are from small, seemingly quite unethical breeders.
That being said, I can't find many hamster products at the best of times. On Facebook Marketplace, it's mainly bright coloured 6 inch wheels, flying saucers & this ball thing ? Looks horrific.
For the cage, I'm set on the PLATSA range as I don't have the tools to properly construct many IKEA DIY cages. I'm also not fond of barred cages as just a personal preference I guess. I'll keep my eyes peeled for cheaper barred ones (the closest one I found was in Exeter) just for a backup cage though.
