I recently bought a Nikon-refurbished D50 which comes with a 90-day Nikon warrantly. I store I got it from, Overstock.com, doesn't sell Mack warranties so I looked into buying one elsewhere. However, I wasn't sure which warranty to buy. I noticed that Beach Camera offers the regular Mack warranty for new cameras for sale along with their refurbished D50s. But when I asked Mack which warranty I needed, they said that only the warrantly special for used cameras would cover refurbished models (and yes, I mentioned that it was refurbished by Nikon). Does anyone know anything about this? The only references here I see are to people buying the regular Mack warranty with refurbished D50s....
