I have looked into getting a sugar glider before, but decided against it because I have cats, and dogs about. I have a friend who has them, and they are very cute. She has 4 males, and I have never observed any bad smells from them. She also keeps her house very clean, as well as the cage.

Have you thought about ferrets? I have had ferrets before, and they are lovely animals. They aren't as fragile either. You can also litter train ferrets. They are very fun pets to have.
