well that's what is so troubling - the fact that Marantz recommended to me PNY and Sandisk, and Goldy is having problems with the 16 gig PNY SDHC card, class 4. I ordered that exact PNY card, but just ordered an 8gig card as well, based on Goldy's problems. my deck won't be delivered for another couple of days, but I'll be testing both those cards once it arrives.
