A Home Brew Journey

So thanks to the starter kit not having all you need to get started I had much googling to be getting on with. First of all what is best to use bottles or a barrel? Well there is no clear answer to this it is really up to you how much money you want to spend and what you prefer.
I opted for a pressure barrel with a Co2 injection kit from Home Brew Online. While I was there I purchased a few other odds and ends like a long mixing spoon, an airlock with grommets, brewing sugar and malt extract. Now including the cost of these items and the starter kit I got as a kit so far the homebrewing experience has cost about £80. I am really begining to wonder if it is all worth it.
