There's 2 companies that make the tanks, one in Canada-that's the good one. The other in Taiwan, not so good. The warranty is the way to tell the difference. I don't remember the exact numbers, but IIRC it's 2 years VS 90 days. Search around, I found a W I D E range in prices for the same product. Most places don't stock them, they just order from the factory and have it drop shipped. They were on backorder when I needed mine
I think they make a run of them and when they run out they wait until they get enough orders to make a run. HTH, Steve
That's the good one!
