Research is very important.VERY.With any animal.& Sugar gliders are no exception.
Some can be messy eaters.& If you are squeamish,some parts of their diet may not be for you.
I recently found out about the "glider kitchen".I'll definately be buying one.Keeps the area around the cage more tidy as if they want to fling food it'll pretty much stay in the glider kitchen.
Some arent messy eaters though.
I'd strongly recommend getting more than one (as you mentioned).These animals can die of loneliness quite easily.
Food must be changed daily as well.
I'm getting a pair
