RE: rear wheel HUBS - Audi Part #8D0501653B / W0133-1600303

I'm replacing the wheel bearings all around, and there are plenty of sources to get front hubs for $75-$85 by Meyle, Ruville, etc. But in the rear, I can only find OEM for $240-$300. Does anyone know a good source for these rear wheel/axle hubs? PartsGeek has 1 for $225, but I need 2. Thanks for any ideas!

P.S. - This part is compatible with 78mm press-in bearings, for cars 1999+ / VIN #s > 800001.

P.S. - Also willing to pay $100+ for a used PAIR of hubs in good condition, PM if you have them to sell.
