You want to BLOCK HITS TO YOUR SITE? WHY?!?!?!?
I know administrators that woudl KILL to have a million hits a month coming in. How much are you looking to spend?
has dedicated servers for pretty cheap, that can handle the load. Why get hit up for $1800+ when you can get a server for much less then that, that can offer 2,000 GB of traffic a month. Trust me, blocking traffic is NOT a good idea, especially if you are selling ANYTHING. Be it selling online, or potential customers, etc. If its just a personal "about me" type of page then yeah its no biggy. But if you run any type of business/commercial website - UPGRADE UPGRADE UPGRADE!
Also has a bunch of links to hosts
