I have found my kegs! Thank you Beeton!
I got in touch with R.D.Strickand turns out he used to work for Cornelius 30 odd years ago before the started his beverage equipment supply business. He has bought and sold hundreds of thousands kegs in the last thirty years (I got a nice history of the business, found out that hoover used to make soda kegs). He was selling refurbished kegs for 50 buck a pop, he has gotten out of the keg business as the supply dried up. He told me he still had about 50 kegs sitting around but he would need to go through them and put some time into refurbishing them for sale. I asked how much he would let them go for if I bought a bunch and refurbished them myself (I was gambling on out of a batch of 10 I might get 3-4 that I could get to hold pressure.) My heart skipped a beat when he said he would let me have them for $2 each.
I am heading to my SWMBO's parents for Thanksgiving this weekend and she wanted to stop to visit a university friend in Toronto on the way there. R.D.Strickland is about a 45 min drive from there. This get me thinking I may be able to sell this to SWMBO: I drop her off at her friends drive up buy as many kegs as I can fit in the Mazda 5 (20-30)?, then come back and pick her up and head off to he parents place for dinner. I thought I was going to have to work at selling this to her(she will not drink beer at all, it took 5 years before I convinced her to let me start building my kegging system)... I expected her to ask why I needed so many kegs... etc... So I prepared my arguments and told her about it. She said that it made perfect sense, before I could use any of my carefully thought out reasons why it was a good plan! I knew there was a reason why I married her.
So if I am lucky I may come out of this with extra working kegs...
