Exotic Marine Systems sold out

[Tom Van Wassenhove]

I was looking at getting a overflow from Exotic Marine Systems for a custom build. went to web page and every item they sell said sold out. Are there overflows in that high of a demand or have they just decided to call it quits and stop making them. If I can still get one dose anyone know what the dimensions for the tinplate are for 32" 1500 Gal. per hour would be? Would like to have tank builders drill holes I have never drilled 3/4" glass before plus it would void warranty.
Thanks for your help in advance.
