If the increased time is enjoyable for you, please ignore the rest of this.
I was interested in all grain, read about it, though about it, but gosh, I don't want to take that much time or spend that amount of money, me being kind of cheap about some things.
Then I read about all grain with Brew in a Bag and decided to get a sample of the process by making a half size batch. It cost me a Corona style grain mill ($25) because the nearest LHBS wutg a mill is 150 miles away and a pair of paint strainer bags ($5 and a pair because they came 2 per package). Gosh, that batch went so easy and my efficiency was pretty high too, not bad for a beginner. Now I found ways to cut down the time it takes even more by streamlining the process and found that I can do an all grain batch in about the same time as an extract batch or to put it differently, should I choose to spend my day that way, I can probably get 2 batches done in the time it takes the traditional mash tun people. There was no mash tun to purchase or build, no stuck sparges ever. Efficiency 80% or better since the first batch but all the flexibility of all grain. Now if I could only justify that wort chiller.....
