Mike and nebrunner, for what its worth, I think you could tuck the cord under the machine to route it a different direction without too much trouble (at least on the Cineplex). It might not be the most elegant solution, but I wouldn't write off an otherwise great machine just based on cord placement if you have found one that you like everything else about.
Oh, and Mike, as far as the size of the machine goes, the 4oz seems to make about the right amount for 2, probably similar to a standard batch of microwave or air-popped popcorn. It works for my wife and I, but I can't lie, if we got a 6oz we'd probably go through that in a sitting too. If there are more than 2 of you I think you might be right in going for a larger machine (or the Gold Medal 4oz which has a large kettle that can cook 6oz packs).
