I recently had a party and my wife said she was thinking about getting a keg. A friend had a mini keg at their party and is was OK but not the same as a pub. I looked into it a bit and i seem the mini keg dispensers use 2L kegs and don't require CO2. I read that the CO2 free feature affects the taste the beer by adding air. This sounds worse than drinking from cans. I tried to look into keg systems but it doesn't seem that keg parties are as popular as they are in the US. I figure I need a keg, hose, regulator, tap and CO2. In order to avoid a coolant modual I can put the setup in a mini fridge. This is when I came across the Keginator. This model is £580 and seems to work with Cornelius Style Kegs. This seems ideal for homebrew. Has anyone build a keg setup at home. Is it worth going DIY or is a prebuilt system the way to go? What do I need to look out for? I would be happy with a 1-2 key setup as I don't really need to have 3 beers on the go (I don't have that many friends, though a key might help).
