look up a store called "How Do You Brew?" In Newark. They either are about to have an all grain brewing class or just had one. Great little shop by the way. I was fortunate enough to be working right down the street from them for a while.

I have heard some bad stories about ordering from them, although I do not have any 1st hand experience with them. They do have a huge amount of diy info to make kegerators.
I can do stainless. I'm gearing up for outage at Limerick so I'll be busy until mid april. If you stiil have these at that time I'd be happy to cut them and weld what you needed.
