Big Berkey filter: where/how much?

[GOVT1911]

I've been thinking about getting a Big Berkey water filter to add to my preparedness stock. I've got plenty of water purification tabs, chlorine, etc and a small Katadyne filter but want to have a nice size water filter that can handle my 3 person family's daily water needs for any emergencies that pop up.
Where are some good places to pick one up and what's a ballpark $$?

Thanks.
