I have not given it much thought but after reading your commet about recient stero systems YOU ARE RIGHT! hahahaha Especially number 3 "Bizarre displays. What IS it with the multicolored flashing lights and rotating circles? I feel like I'm trapped in an episode of Star Trek" I was travelling up to Mammoth with my cousin and he has one of those nice brightly lit faces and it was sooo annoying after a few hours that we had to put a wendys bag in front of it to block out some of the light... It was bright enough to actually allow other divers to see our faces when they passed by...
