I have 6 ball lock kegs (bought back in 2003, used), and 2 of them have seen better days. Much better days.
So, i splurged on some new kegs. As in, brand-new.
AIH was (and may still be) running a sale on new 5-gal ball lock kegs for $75/keg, instead of ~$120/keg. I got 4, + $16 UPS ground shipping to Cincy.
I'll probably keep futzing with the 2 wonky kegs, but it was time to finally get some new kegs.
