Ive had a dedicated box with SM for about 3 months now. They are pretty rock solid, and my site has never gone down. But a word or advice....their Tech Support sucks ass. All but a couple guys over there are worthless and know nothing about the configuring the services that come with the plan (horde, squirrelmail, urchin..etc). And they can be kinda rude too. But if you have your own admin or dont need help setting that kinda shit up...theyre a pretty good choice from what I can see.
