Cheap minecraft server host?

Does anyone know a few good, not too expensive minecraft server hosts?
I'm going to make a bukkit faction/PvP server for about 25-40 players, or 1-2 GB of RAM.
If possible could anyone give a promotional code to go with the hosts listed because I'm not too keen on paying excessive sums of money.
Thanks.
