heater blower motor replacement on 2001 Volkswagen EuroVan

Hi, my regular shop diagnosed a fan issue - the heater blower motor assembly needs replacement as the shaft is bent. Should this cost about $900? Their est. included a new VW part - is a cheaper aftermarket assembly a bad idea? Their labor est. is many hours - is this correct? If this is really a complicated job, should I consider taking it to a dealer(closest is serveral hours away!)? Thanks, JRP
