Hey Anteek
I get what mrTbeer and PeteQ are saying, and having never tried AG beer I can't dispute "if you want quality beer".
You asked the question about AG so I assume you have the resources (money, time and ability) to proceed at a timely rate and produce a good beer first up.
Personally I see the process as a progression, but one that could easily skip the kit and kilo phase. I mean you could go straight to full extract brewing and IMO produce a good quality beer. This will enable you to get familiar with sanitising, mixing, boiling, steeping and fermenting processes (not that they are that difficult to understand or get the hang of).
Having brew K&K, Kits and bits and full extract I can honestly say that each time the quality of the beer has shown a considerable and consistent improvement.
