I bought my last two from a gal who now lives in Douglas, Wy.. I have had seven goldens.. They are beautiful friends and great hunters IF you buy from the good kennel.. I have heard of Sunggold, but never bought from them.. I'll contact the gal at her new address if you like.. Her dogs are NOT cheap, but they are wonderful..
http://ponderaygoldens.com/index.asp?ID=3WCH, lots of Sungold in their lines and I suspect your dogs' pedigrees will reflect that.
For the OP, Field Goldens will not look like the big blocky, long haired (mostly light/blonde coated) specimens shown on dog food commercials.
Those are show dogs and are not bred for hunting drive, love of water, athleticism, nose, stamina, etc.
