To be fair, I've never heard of TMM (NATS) ever being totally unresponsive to anyone. For a while, they were a little slow, and they used to have almost no support on weekends or evenings, but that's improving too.

It's not that their support is bad, it's just that you never get the sense they *appreciate* your business, and I've heard that from programs 10 times our size. I've never gotten the sense they take better care of bigger programs over smaller ones, just that, in general, they are a bunch of tech geeks with a good product and reasonable support, but no sense of what it takes to make customers feel good about spending $150-700/month with them.
