When I first started off w/extract I got my recipe kits from them. It's been a while, but I think the IPA wasn't hoppy enough for me, so you should try their double IPA. Check their website for customer comments on the individual recipe kits. Also, their kits tend to be a little low on the carbonation side, and they readily admit this is intentional, so you'll need to adjust if you want it more carbonated. However, all my batches came out pretty good using their stuff.
William's will ship the same day as long as you get your order in by 4pm. They are a very reputable and good company!
