I'm up to brew 15, of which I would say 1 was totally undrinkable (brew #1), and 2 were average at best. Brew 8 was the turning point of good to great.
What I did was buy enough ingredients to do the same recipe over and over. It was Dr Smurto's Golden Ale, but you pick whatever you like. Then just brew that one recipe until you get your process sorted. Yes it will be boring drinking the same beer over and over but at least you rule out ingredients and beer style as a contributing factor to why things don't turn out so well. Get your processes sorted before embarking on many different and comples beers. You will also see how different processes (i.e late hopping, over bittering, no chill) have an effect on taste.
Work out your process, get to know your equipment and then the flavour will improve considerably. By chopping and changing recipes, you don't know if it was your process, equipment, recipe or ingredients which failed.
