Roborovskis - One Hamster or Two?

[Griel]

Hi, I've always read that most hamsters in general are solitary creatures.

But for the Roborovski, I've seen a lot of information saying that they are social creatures and should be kept in pairs.

The Hamster Central Wiki on Roborovskis says "...they are social animals and should be kept in single-sex groups or pairs, preferably from the same litter."

Should I look into getting another Roborovski to keep my existing one company? What would make her happier?

I am really keen to get a companion for my existing Robo. I am able to separate them into different cages immediately if I see signs of fighting, but I would prefer it if they were able to live together. Can anyone give tips on how to introduce one Robo to another? I've read up some, but hoping for more advice.
