The first batch is always the most memorable. I'm guessing your LHBS guy is annoyed that you won't be buying any of the 5 gallon kits he has to sell. As a consumer, you're the one with the choice in who you do business with.
Anyway, I switched over to small batch BIAB a few years ago. I can do everything in my kitchen, which is a huge plus because A. I can't have a propane burner where I live, and B. I can still do full volume boils. In addition, I'm able to use a repurposed mini-fridge I got cheap (like a tank of gas) from some graduating college kids that were leaving town. A 3 gallon Better Bottle fits snugly with a blowoff tube, so no more worries about fermentation temps. I could fit a second one in there if I wanted to.
I'm also glad to see that I have some brethren here that don't drink enough to justify 5 gallon batches. I might drink three or four bottles a week, but I prefer it to be as high quality as I can make it. My days of housing a 12-pack are well behind me. So now I can brew every six weeks or so and still have plenty of beer to give away and share. Besides, I think I enjoy the process as much as the end result.
I was at a homebrew club meeting a few months ago and a guy brought some samples of a pepper stout. This guy is a fabulous brewer and the beer was *amazing* but it was still a novelty. I'm like, what in the heck are you gonna do with 5 gallons of this other than let it sit in bottles for a few years until you dump it out when you get tired of looking at it. Still delicious, though.
