We run a 1:450 scale earth map. It includes the basics, like Towny, TheNewEconomy (with gold ingots, mineable currency!), and a few other fun ones like the hat plugin and 3-dimensional dynmap.
This is a no-payment server, so there are no donation sites, no purchase-able ranks or items. Just pure Minecraft. The server is stable and privately funded by the two owners, and we have no plans of shutting down any time soon. It has been prepaid for a year already, so you can play a little, play a lot, and never worry about your builds expiring or the server shutting down.
Plugins installed on server: Towny, Siegewar, Hat, Lore, Dynmap, Marriage
