Today there's a new CPPS I'm sure you might enjoy this one. It already has custom items on it's first day out! This server is called Penguin Phun'! Talking to the owner he said there will be custom soon! Also it's a VPS (Virtual Private Server), so you don't really need to worry about that much down time! Penguin Phun has a few custom as it also allows !SMP, !MYP, !SS, and !GL commands Oh, and there's sliding!
Thanks and enjoy your stay!
