Glad you're ok. This is exactly why I switched from glass carboys to plastic ones many years ago. My current fleet of eight primary fermenters consists entirely of 7 gal Fermonsters (without valves). I love these fermenters--light, unbreakable, lots of headspace, super easy to clean, yada yada yada. PET plastic apparently does allow for a small amount of oxygen ingress, but--and I'm not trying to start a debate here, and I suspect that some folks on this forum will tighten sphincters over this--the small amount of oxygen ingress that supposedly occurs with plastic fermenters has never, not once, perceptibly affected my beers (although granted, it's rare if I have a beer on tap for longer than 3-4 weeks; again, not trying to start a debate about plastic vs. other fermenters). Brewbuckets are nice, but you could buy 6 Fermonsters for the same price and I guarantee your beers would turn out the same.
