I have a very nice dedicated server with Cpanel for $105 a month from Hivelocity.net, I'm not sure exactly what the specs of the dedicated server you need however they have very good pricing in all of their servers.
Knownhost has good pricing on managed cPanel VPS plans. As does jaguarPC, I think. If you're attached to a dedicated server, a lot of companies are offering intel atom PCs as a dedicated server.
Limestone rocks for sure, my reseller site is hosted under them i know it for 3 years excellent service no downtime so far.
you can buy dedicated from http:// theplanet .com/ dedicated cost more.... if you have some little needs then use some vps
