I've been looking at all the for sale posts for cameras, and notice that the used prices are not that far off the new prices. For me, a big point is can I get warranty work done if needed on a camera I buy used? Do Oly/Panny allow for the transfer of warranties? I guess if the seller still has the reciept & card, it isn't a problem since the companies wouldn't know or likely care who actually paid for the camera the first time. Thanks.
