In California chards, at the $25-30/level, Rombauer or Frank Family are pretty safe choices. As for higher end ones . . . well, I'm a "red-man" too, so I wouldn't spend any more than that on a white, so I wouldn't know.
You should perhaps note that, due to criticisms Cali vintners received in recent years, and a subsequent switch by many consumers to Sauvignon Blancs, Pinot Grigios, etc., they have been producing many chards that are less oaky and buttery than in the past. Ask you local sommelier what he'd suggest.
