I have been given a King Keg which needs a bit of work on it to make it usable, it needs a new tap and float assembly, a new O ring for the cap and a replacement CO2 valve as the one it had has no pin in it for the gas bulbs, once I have replaced all these things I will have spent over £25, I can get a new basic barrel for not much more so are King Kegs that much better than a basic barrel?
