lol fuck 1grand for a used top and that group buy was in 2006 buddy.. did get ahold of john from ameripol and they are very much in business still and THEY DO still have and make the glass top for del sols... cost lil over 600 brand new for one...
Far as scratching it you dont have to worry about it.. its not actually glass.. It is a type of plastic.
They have actually demoed it trying to scratch it with steal wool and all. you would have to try really hard to scratch it... mine will be shipped this monday...
