Chins can be quite expensive, so I would advise letting your parents browse through the health and hygene section, as if you get a boy, he will need routine hair ring checks.
Keeping them cool is a BIG deal, so dont take that one lightly. Make sure you have a good feed, not that kaytee crap. Get Oxbow, PanR, Mazuri, those off the top of my head are good ones.
Your chin will need a ton of things to chew on, and plenty of leaper shelves and an adequate pet cage. I dont feel that most cages from the pet store are adequate, check martinscages.com or get a Feisty Ferret or Ferret Nation and you can deck it out.
If you do a search for Ferret Nation Club on here, you can see all the cages. Oh and Quality Cages, they make awesome cages, totally decked out with proper shelves ( although I would add more) and a wheel that is good.
Plastic wheels bought at the store, IMO, are not big enough or sturdy enough, you may as well get someone to fork out the money.
There is a lot that goes into chin care, and I would seriously have your parents look at this site, and have them make a better informed choice about getting a chin, as emergent care can be needed, and more then not I see people posting on here about a sick chin and the parents wont take it to a vet, and that is heartbreaking.
You can check out the classifieds here, and ask your parents to get somethings from the sellers here that are chin safe and better then any store bought items to add to your chins cage.
Good luck with your new chin.
