have decent servers, all on SSDs etc. Not updated to beta yet though as they're waiting for the latest release on hMod which enables the servers to be controlled via their control panel thingy. You can backup worlds, restore them, and reset them all at the touch of a button, with loads of plugins just ready to be installed.
£8 for an 8 slot server a month. I'd let you on mine, but people can't be trusted so it's just for friends :D
