Hot Thai Kitchen has a recipe so you can make your own which is more closely related to the original than that which we get in the US.
Some years ago, there was a local company producing a sauce that was supposed to be more like a Thai version. It was certainly not as sweet as that "Rooster" sauce that's so popuar these days. I've not seen the local sauce in a while.
HTK is defintely worth a look. Her ingredient list is just about identical to the locally-made sauce I mentioned.
