I tried the Just the Cheese, Low Sodium Cheddar. They were pretty good, but tasted just a little bit stale. I figure they're not worth the hassle, when it's so easy to make your own. I find that shredded Parmesan works best, cos the cheddar just oozes out fat. I tried Jalapeno Jack the other day and same thing, didn't hold its shape too well. I understand that there are lots of cheeses that work with this and I imagine you could use a low-sodium cheese if the salt worries you.
