Where can i find a soft top for my chevy tracker?

My boyfriend and i have a 98 chevy tracker thats in need a soft top and we need some web sites that we could order from that would be of quality and affordable, we tried ebay but there wasn't anything on there that was compatable with ours, so if anyone could help please do, and we were hoping for something that would be under $300, we are a little tight on money so sales would help also
