Query: SanDisk 31 - PNY 0 - Play it Safe

Over the years I've purchased a great number of SanDisk digital cards for my Nikon and Canon SLR's. I've never had a problem with SanDisk cards (Compact Flash, SD, or SDHC. I've only purchased one PNY card for my camera (a 4gb SDHC model).The PNY card failed after about 20 hours of use - "read error, and will not format". I lost several pictures on some personal work - thank God not a client.So this is not necessarily what you might expect - but for me I'm sticking with SanDisk - why take a chance?
