I had a very similar experience to the original poster, the main difference being that we were using their top end nitro package. We left after we realized that for the same money we could actually get managed hosting. We moved to Neospire, and I've never looked back. I've never had to wait longer then 5 minutes on a support call, and their support has been fantastic. They actually called me when my server load was high and assisted me in tuning the server. To be fair to MT, they are very clear about their service -- "we'll rent you a box, but don't ask for admin support."
