If the air cell is well made, then this looks like a great tank. Whats the cost?

most wine presses today are made this way [just no top on the tank]

The last few house I have had I installed those. I never had a problem but have had one in use for more than 5 years (I move a lot). So I have no idea how long they last.

That tank is installed in my house and I haven't had any problems. The company that sold me the tank said he has had no callbacks since installing them in commercial and residential applications over the past 8 years (i think it was 8 years). Seem well built to me...
I haven't had to replace the bladder and I havent hardly needed to add air. Also, it was nice and LIGHT!!! Much better than the water heaters I had to lug downstairs...

In my experience they don't hold up well at all. Anytime a tank has a replaceable bladder I get very leary of it. The fiberglas does not hold up well in the sun either. If in a basement or pump house that wouldn't be a problem. Flexcon also makes a fiberglas tank and I won't sell them for the above reasons.

around here there aren't any in the sun. Too cold and would freeze so they're all inside. That might be the difference.

The main advantage seems that the bladder when without air will simply be squashed flat, not over extended, thus not broken and with out a dome inside to rust and rub on the cell. Looks like the bladder is a simple exchange, not the hell of the bottom exit bag type. How much money?

The prices seem reasonable, but I didn't see prices for the replaceable bladder.

I would never buy a tank that has a replaceable bladder. The reason they are replaceable is that they don't hold up. Take a piece of paper and crumble it up then open it up a couple thousand times and see what it looks like. The same thing happens to their bladder every pump cycle.
