Right now I have a maytag skybox. I am having the same problem that you had. The kids can't drink a whole can of soda and I really don't want them to either for that matter. So we have some decent waste. I am looking at adding a good bar gun and using the Maytag for specialty drinks that I can't get syrup for. e.g. Virgil's Root Beer.
I have thought about adding a breakmate for my office here. I don't think I want one in my theater room as I fear that the system will be a bit too noisy.
