Sadly, I can't post a link to it, as it also permits playing without paying (I've paid though).
If you want to run the server on any other OS or without GUI it’s a bit more involved.
If you run into memory issues, try launching it with java -Xmx1024M -Xms512M -cp net.minecraft. If you’re running on Windows and just want to set up a server easily, download Minecraft_and run it.
A launcher that lets you choose however, is much, much nicer.
I found a decent launcher which includes both this and a nice world/installation backup manager.
