I've been minikegging my home brew for a few years. Last year, someone gave me a Krups BeerTender mini-kegerator. Nice unit! Problem is that it is completely dependent on purchasing minikegs that have built in CO2 dispensers. And the problem(s) with those are - they are not reusable - they are expensive - they dispense mostly foam - the beers available in them, Heineken nd Newcastle, are inferior. So I will retain the dispenser tube end. What I need do is use an external co2 source, such as the paintball containers I using now in a portable setup, to charge the kegs. It'll likely occur early next year. I'll post pics as it progresses.
