Our big problem in the US is this damned law about pasteurizing cheeses. I'm surprised you could find a decent camembert, since a cow's milk cheese needs 60 days of aging to be sold unpasteurized.
That said, we make some wonderful cheeses here, especially goat's milk ones (e.g. Humbolt Fog), blue cheeses (any number of varieties here, e.g., Maytag), cheddars (some vermont cheddars are wonderful) and so on. They can't compete with French cheeses on the price, however.
