Cmo,
Glad to hear your reaction to the Airy 3-SB. I know two other guys who went from Grado Statement Ref to ZYX R100 Fuji or higher. Their reaction was the same as yours.
Your longevity concerns re: a Teres were well addressed by C123666. Sourcing another wood platter would be all but impossible, but there are few other items of concern. The bearing would be expensive to duplicate but a Teres bearing should last about 1,000 years - unless you do something really stupid. The ball and thrust plate will wear, but those are easily obtained or made by any machine shop.
