I've been in there several times. They aren't physically large, but seem solid to me. I'd say their ingredients (malts, extracts, yeasts, hops) are better than their equipment, but they have at least one of everything.
I haven't noticed their kits, but ingredients seem on par with everywhere else. I believe they normally stock Better Bottles, but don't have them on their website. I'm not certain of this---the first time I was in there I asked about them and was told that they normally stock them. However, this was during the end-of-year inventory reduction sale and a lot of their equipment was sold out.
I don't think they update their website super-often, so it's a good idea to call them or stop in to see what they've got. The help there has been very friendly and helpful to a noob.
