Best minecraft server hoster?

Well the biggest minecraft server host is Multiplay gameservers: http://www.multiplaygameservers.com/?r=LAL599. I also have my server over there. They have servers in 29 places around the world. The server will be set up within minutes and their support is really good. Also you can manage your server with ease, you can add pre-set bukkit plugins with few clicks or even mods like Tekkit. YOu also get free voice chat server and webspace (for websites or mySQL database)
I've been renting my minecraft server from Multiplay for over a year: http://www.multiplaygameservers.com/?r=LAL599
