my system run through a reseller from theplanet.com they have good rates, $99 for a dedicated system a month. Dual system, 500 gigs bandwidth, 80 gigs space etc. I've never had a down time, cept for ip change.
the tech team I deal with, has been awesome as well.
before them I was at rackspace.com, they rock the boat as well however they are 4x more exspensive. And my current box I get all the same level of support but free tech support, where as rackspace for the same stuff was $75 an / 15 mins ... eep
:P
