going to let go 2 1/2 BBL converted kegs-legally purchased at beer distributor about 10 years ago. pulled the trigger on 2- 15 gallon megapot 1.2 pots with a 20% coupon. both have welded bottom draining 1/2" NPT pipes to attach a valve. picture is for reference. they served me well for many years. i was thinking $100 for the pair. too much, too little?
