I actually drilled a hole in the top of a 1 liter soda cap then hotglued an ez-caps on top of it. The caps found on 1-liter Pepsi bottles fit perfectly on the tap-a-draft kegs. I have notice that you can usually drink half of a 2-liter bottle and still have a little carbonation left in the remainder up to a week later. I like mine well carbonated though so I just pour it all into my miller fridge/tap-a-draft kegs and force carbonate it. Those Miller & Coors fridge draft kegs are almost identical to the tap-a-draft system. The main difference is that they are made with a thicker plastic and that they use a single 16 Gram C02 cartridge instead of 2 8 gram cartridges. The bottles are interchangeable. In fact, I just bought an drank a couple of the Coors fridge drafts, then place new cartridges in them and bought a bunch of tap-a-draft bottles from Midwest supplies. The only thing you need to do is take a vice grips or rubber strap wrench to twist out the cartridge holder after the original is spent in order to break the holder locks. Which I must add are nothing more than a couple of small plastic tabs to discourage you from twisting it out and reusing it over and over again.
