Not sure how close you are to Wyoming (the town in RI) there's a place right off 95, just called Craft Brew Supplies. Here's their website http://www.craftbrewssupplies.com/
The guy who runs it, Chris, is nice, you can email him your recipe before you go and he'll put together the grain bill. They have a good selection of Brewers Best kits and a few from Rogue as well. He also has all the odds and ends you might need at the last second.
