I could say that for dedicated servers I would rather prefer deals from a2hosting.com or cheaper serverpoint.com - both companies are quaite reliable and really well reputed by the clients, offering wide selection of deals and being professionally supported.
I have heard hqhost.net has stable servers and their reputation is reliable. Dedis are well-supported and monitored.
One more company can be good for your needs - glowhost.com, they offer dedis at affordable, they are unmanaged and managed.
I see that hqhost.net is a popular company among the web masters, I have read their their services are reliable and well-supported.
They offer some new offers constantly.
@ OP, you can check out the stability of hqhost.net servers just trying them.
They offer a summer special now and you won't spend much money on buying a dedi from them.
Really good uptime is given by serverpoint.com. I recommend this host to you - never heard any complaints about the service. The experienced and inexpensive host!
