I was pretty underwhelmed when I went there. The Brewer's Best kits are convenient, but the selection was.... limited. I guess that's a product of the market: Maybe most folks here don't want to try brewing a complex brew, and he stocks what sells (which, if that's the case, I can't blame him. The man needs to make a profit, no?)
Biggest gripe, though, really, is the lack of yeast options. Maybe it has changed since I was in last, but he had two types of yeast: crappy, generic, dry "Brewer's Yeast", and another type of crappy, generic, dry "Beer Yeast". No liquid yeast. No Safale -05. No nothing. Just two types that I could get at my local grocery store.
So, yeah... I wasn't terribly impressed. It is nice to have a place close by where I can get bottles, caps, sanitizer, carboys, etc., though. But if I want ingredients, I'll swing into GF when I'm on lunch break in Indy.
