I wouldn't use the rubberized ones with electric either. I'll be going 10g electric sometime soon.
This may be too much to ask, but will the guy let me come, choose a straight sided keg with no rubber, and have him plasma-cut the top. I'd pay $75 for that.
Or Brew, if you can get the top off of it, I'm interested.
I'll take one, I want to come down in person and choose it though.
Once you have a firm price, bonus if its lower, send me a PayPal link in the PM and I'll do that for one keg, or I can do cash. Also, I owe $14 for StarSan, can you send me a PayPal link for $14 + 4% to cover that?
