Nothing wrong with RM Willaims, V8's or oversized mud flaps (you might thank someone one day for having big mud flaps and not spraying your windscreen ). I still don't get the premix drink thing, but that's because I like Rum, though the kegs sound interesting.
Edit: whats wrong with utes? I have one h34r: Good for picking up sacks of grain
Corbo asking a homebrew/craft beer forum for where you can get XXXX is asking for trouble. However you will find out how to make your own beer as good as and better than XXXX here :super:
To clean/fill them, you need some plyers to grip the ring from the spike and rip it out, it takes some force and is a little dangerous. When the ring is out, the spike just twists and pulls out. You can then clean and fill, then pressurise. You will probably need a shut off valve (impossible to find) for pressurising through a coupler. When you are done, just put the spike and ring back in the same order.
Its pretty much a matter of getting used to it, with practice, the're just as easy as post mix to use.
