OK, I'll do it. This is a very touchy subject around here.
What is different than buying one is that they cost the brewery close to $200 each and you only put down a $30 deposit. Technically your stealing the breweries property. You are only buying the beer inside and borrowing the keg to drink the beer. The implied contract is that you will return it when finished. The deposit is intended to encourage you to return the keg rather than take it to a scrap yard. There are legit ways to acquire a sankey keg but stealing one is not something that is considered appropriate arround here.
ahhh... i see... i didn't know they costed that much. Thanks for the info. I guess if i ever feel the need to get a sanke ill know for the future. I guess that makes sense though since a new corny is at least $100
