Depends on how choosy you are. You can get high end alloys from Brazil or opt for the Chinese ones.
For Quality Chinese,AutoExpress shops (MSA Road,City Centre e.t.c) is the place to go. Remember to consider how much load your vehicle will be susutaining regularly. If used for heavy jobs on bad roads,just keep your chuma rims-its much SAFER and cheaper. You can also order specific alloys for your brand of Car e.g toyota,Subaru,Mitsubishi e.t.c on ebay
