I bought the Stainless Big Berkey (I think that's the model)... It is the stainless version that is comparable in capacity to the "Berkey Light"
A good friend of mine has the Berkey Light and they are definitely more durable than you would think they are from the photos, but the stainless ones are designed so that the top portion can be flipped upside down and stored in the bottom portion for transporation, and stainless just looks much nicer.
I got a package on Ebay back at the end of 2010 that came with the Stainless Big Berkey, (it is about 1.5 to 2 gallon capacity) — and also came with 2 black berkey filters, 2 of the Flouride PF2 filters, and a sight glass spigot.
They also give you the regular spigot with the package, so if the sight glass spigot breaks (my son is constantly moving it and I think eventually someone is going to F it up) — you have a backup until you can get another one.
I don't remember what I paid but it was the best deal I could find for sure.
The black elements last a very very long time. I forget how many gallons, but I think I have a few years before mine need replaced.
The PF2 flouride filters don't last as long, maybe 500 gallons? I still haven't replaced the ones I have yet, but I might replace those this year sometime. The water still tastes awesome.
I had to see one in person before I would buy one and it took a long time before I saw someone with one to check it out.
My son had high lead content in an early blood test so I bought one the next day. Next doctor checkup, no detectable lead in his system so that was good enough reason for me.
I am in a family of 4 people and we use it for both cooking and drinking water. It takes quite awhile to filter a couple gallons of water, so we constantly fill up empty plastic jugs and store them, or keep them in the kitchen for cooking purposes.
Hell, just last night on that Doomsday Preppers show I saw the couple filter the water out of their HOT TUB with one of them and then make hot chocolate from the water they filtered...
I've never done the food coloring test, but I've seen videos of it on YouTube where people who seem legit have done it and showed the results.
If I knew someone I didn't like owned one I would try taking a leak in one to see if came out clear underneath but you won't see me doing that to my own anytime soon ;-)
They are pretty bad ass though. I've had this one for over a year and the steel cleans up great and looks brand new whenever I wipe it down.
The ONLY complaint I have is that the PF2 filters thread onto the threads of the black filter elements and you have to be VERY careful because they do not sit tight, and turning them too many times you can rupture the PF2 filters, or screw up the black element filter threads.
I would strongly recommend thread tape wound around the black filter elements before putting the PF2 filters on, which I didn't do myself but will when I take it apart for a cleaning sometime.
Also, "priming" the filters the first time is a bit of a pain (they give you instructions) — but important. I find that once you run a gallon or two through the filter, enough standing water remains at the bottom of the top portion that the filters do not need to be primed again. If you don't prime them, the first few gallons you filter will take FOR-EV-ER...
They still take forever after the fact, but I can get a glass of water out of the bottom within 15-20 minutes of pouring water into the top.
You drink some Berkey water for long enough and you won't drink anything else. You will be able to taste the nasty crap in just about any other unclean water source you come across after you get used to drinking the clean water these things put out.
