I've found a few reviews of galvanized tanks from Liland on other makes, generally positive. But nothing on their stainless steel tanks or specifically E-Body tanks.
I have a Spectra also, and it looks good, but I'm still unhappy that it is not in fact a proper reproduction with the internal expansion tank. The vent connectors on the outside look ok, but I don't know if they properly route to all corners inside the tank. It'll be a while before the car is ready for the tank so I have time to research alternatives.
