I applaud your desire for good USA made glass and yes, I believe that while Chinese glass is very affordable, you will likely run into quality issues with fit and finish, IMO.
Also, there is an open Tsunami thread and perhaps you would want to consider making the same post there.
Assuming we want somewhat affordable production glass and not high end, artisan specific pieces, I like Huffy Glass and have had them custom make me a glass dab station for a pretty affordable price
Also, I would suggest C2 Custom Creations of So Cal. They are another affordable, USA production house. I have one of their pieces and its very well made and was very affordable.
