Buying a second chin

I bought my chin four months ago. I really want to buy her a buddy though. If I did I would buy a girl because I hear you should pair chinchillas with the same sex??? The only thing holding me back is the fact that I don't want to buy another chinchilla for them not to like each other. I don't want to deal with having to sell the new chinchilla right away.



Any advice?

And, how do you feel about only having one chin? Do you feel it's necessary to have multi chins so they can have friends?
