I use RedSpeedServers.com and they provide such reasonable prices with DDoS protection. They've been having some down time with there datacenter, so they switched over to Dallas, TX and provided free DDoS protection.
As for getting a maybe like a Dedicated such, I recommend getting nfoservers.com VPS 2 core. Its the best one to have to hold some number of servers. I hosted 2 PERP servers, 1 DarkRP, and 1 Build servers with no lag at all. Of a course the servers wernt fully packed.
They don't advertised DDoS support...
