Kaytee Clean & Cozy and Carefresh are both great, but I know that definitely the latter is expensive (and maybe the former too, I'm UK here). Ordering online is useful (if you can get free postage as the size/weight of bedding makes it too expensive otherwise) - Aspen woodshavings and hemp substrates are good but difficult to find in the US if they're not online. Maybe have a look to see if Zooplus ship to you because they have hemp bedding.

In addition to a main substrate you can have areas of sand or soil which may be useful if you have to fork out lots for bedding. Litter training your hams will hopefully reduce the amount you have to remove, too.
