zyGRIB
This is a new GRIB file reader with fully automated GRIB file download (internet connection required). It's a French piece of software, but the language can be set to English. As far as I know this is the best stand alone GRIB file reader at this moment. The product is still fully under development, so check for new versions regularly.
