I think going from cheapest to more expensive, it goes: Megazorb, Aubiose (hemp bedding), Kaytee clean N Cozy, fitch.
to be honest, i think all of them have dust problems to a certain extent, but I won't use carefresh due to it being so dusty it made one of my hamsters eyes close up so she couldn't see. It's also very expensive.

Some people are allergic to hemp - but not heard of hamsters being allergic
some people don't like the smell of megazorb or the hemp bedding but that is something you just have to work out for yourself by trying them.
