I have a speck case for my kindle keyboard, in particular this one
http://www.speckproducts.com/tablets...-keyboard.html. It's a very hard case. They make one for the kindle touch but it's different and I dont' know how sturdy it is. Basically look for a case that it locks into and that the cover is really thick and hard and folds back on itself. It makes it heavier but it's more protected. BTW I didn't spend that much money on the case. Target had it on clearance for about $12.
