I did enough reading before I got started to set my sights on swapping to BIAB after a couple of extract batches. All my equipment was purchased with that change in mind. The only thing lacking for me to start BIAB is the bag itself (and maybe a mill). I have an elevated SQ14 burner, a 16 gallon kettle, a march pump (currently used for whirlpool cooling), and a full sized refrigerator controlled by a STC-1000.
As it turns out I have brewed about fifteen 5 gallon batches in the year or so that I have been at it, all of them extract. Not because I fear AG, but mostly because I really like the 3 hour brew day. I am a 66 years old and don't have the stamina that I did in the past but I am drinking excellent beer that I brewed myself from some damn fine extract kits. I do full boils, whirlpool/immersion cooling, yeast starters, oxygen stone, and temp controlled fermentation. I bottle my beer and have no plans to start kegging it. My beer is good enough and cheap enough that I have no desire to add hours to my brew day for the sake of all grain.
Besides this allows more time for my other hobbies which preceded brewing as well as making many of the brewing related diy's a snap.
As for comparing brewing to driving; I started driving a John Deere 40 which of course had a manual transmission, at a very early age. In fact I could not reach the clutch and brake pedal from the seat so had to drive standing up until I grew taller. Next came the one ton '56 Ford truck which had a 5 speed bus transmission and several other standards. The first automatic I ever drove was the drivers ed car at the high school, but I had been driving standards for several years by then.
Some day I may brew an all grain batch just to say that I did it. But there is no way I would expect to get a better beer than the stout that I am drinking right now that I brewed from extract several months ago.
