Just want to toss in my opinion, I agree very much with OP. I was very much intimidated by everything from the terminology of all grain, brewers complicated rigs on here, and the simple fact that it was regarded so highly. When it came down to it, you can easily go from Extract to All grain with a bigger pot and a strainer bag (using DeathBrewer's Stove Top AG method) or build yourself a home depot mash cooler for 60 bucks, and you're all set. I brewed ~80 gallons in a month an a half this summer once I finally completed my mash tun (did the stove top method for a while) and it couldnt have been any easier! Those 80 gallons easily paid for my equipment upgrades.
Just go for it!
