I've never fooled with gamma lids, the rubber seal that the lids I have seem to work just fine for me. Then again, getting me to pay money for something I already have and works is like pulling teeth out of a chicken.
Yep.Like mentioned,I love the gamma setups,but in hindsight,I fully agree.I could have done the same with regular food grade buckets and gasketed lids for much,much cheaper.
