Looks pretty good, I'm also in Milwaukee and will soon be upgrading my kegerator to a kegbot. The setup currently has a older microprocessor doing temperature control left over from an older setup which i will be replacing. The old setup was very similar to kegbot but used a scale to weight the keg instead of a flow meter. My setup is a chest freezer w/ 2 half barrels. I'm still trying to decide if I'm going to go with an RFID tag set up because i don't know if i can get everyone to actually use it.

That's great, another possible kegbot is always welcome news to hear.

I am of the opinion that "if you build it, they will come". I really had no problems convincing my drinkers to use their RFID cards. If they don't it's "No Beer for You".

Cheers,
Geoff
