I can not use BuyVM. I already have servers with RamNode and SecureDragonMid/west coast USA would be BuyVM, RamNode or SecureDragon. They've all got filtering on the west coast via CNServers I believe. Get a 256MB box and install DNSOnly and have at it.
Looks like a good deal but not enough zones.What about using a ClouDNS DDoS protected nameserver as a slave DNS? They're having a birthday sale: $2.95 monthly (gets you up to 2 nameservers, 50 zones/unlimited records) or $10.95 monthly for 250 zones. DDoS protection is 10Gbps.
