Mac hosting doesn't tend to be VMs largely because of Apple's licensing rules for macOS (which is a big hassle, no question) so they'll naturally be more expensive than a $5 virtualized Linux VM. But Macincloud has ~$20/month plans (with 8GB of RAM which isn't a $5 option for most Linux or Windows VMs) and there are several others going for between $30-50, so you hardly have to go with $80/month.
