Greg, tkl, Rifter, Al, Tombeis, Stingray, and SFM6, Thanks again for all the great answers and help. I was originally thinking about getting a "Borofloat"(?) or SuperClear(?) lens of the proper G2 diameter? Am I saying these names right? And where have I hear them from? I peruse everything here and read all the words, and then just as quickly forget where I found everything...
It's just that if the lens alone is only a buck or two, I really do not need an extra bezel since the replacement glass lens will be permanently mounted (no reason to go back to Lexan).
