I'm am POSITIVE these scales are available in the States, in fact I know they are, I've seen them somewhere,
You have SO many online cooking stores, - remember that the population of California alone is larger than the entire country of Canada, yes really is true ! .... so we have very few online stores here for that stuff.
I have 2 scales. One is a new one from that website and is accurate to 1 gram ! ... that is AMAZING !, nobody needs
that in reality, but I use it for brewing and hops are very very light, so it's great for us homebrewers.
If you are baking, 1 gram accuracy is overkill, many scales are accurate to 5 grams ( I don't know what that is in oz... )
