I agree the good ones are from Costco. I think it only has soy lecithin in it, and doesn't use soy as a protein source (it uses primarily rice and bulgar?) It does have cheese, however, so if you're vegan they're a no-go.
I gave up trying to buy locally and just make my own usually. It's pretty easy to do. Black bean burgers seems to be about the best IMO. I use this recipe usually:
