I'd have to disagree on the MSR Blacklite. I've had mine for a long time and it's very durable.
Mine didn't last very long, coating and the pot itself. They're not as durable as the Duralite, which are hard anodized. (they don't call it dura for nothing!) You can get the same hard anodized for almost half the price with the GSI, and they have a non-stick coating too.
