For clubs to make the investment in tanks for shows, they do look at the long term life of the tank. I haven't yet seen anything that holds up for long if you allow them to be dragged around with a small bit of water in them to clean when tearing down. Yes, the price is good, and I too have known Lam for quite some time. After talking with him about these tanks, they seem like a good investment versus other brands out there currently. Again, as long as someone is in charge of tearing down the show makes certain that folks don't just drag the tanks around for cleaning, I think they'll hold up for several years. After all, they're only used once a year (usually).
