Wanna get a sugar glider!?

So I want to get a sugar glider and have read up on how to take care of them and everything but I don't know how big of a cage I should get it. So can you leave me a link to pictures of a cage that's big enough for one sugar glider? Cuz ive tried to look on pet stores websites but i don't know how to look up or what it would be under. Also do they smell alot? And if yes is there something I can do to prevent or lower the smell?
