Affordable wheel for chinchilla

Hi, so I am hoping to get a chinchilla soon and I know a wheel is a must. However, I’m having trouble finding one for an affordable price. Everyone raves about the Chin Spin but that retails for $120 and I just can’t afford that right now on top of buying everything else for the chinchilla. I’d like to get one eventually but in the meantime I’m looking for an affordable wheel for my
Chin. I don’t want one made of plastic and I know they need to be about 14” in diameter. I’d appreciate any help!
