There's Corrados in North Jersey (Exit 151, around there, off the Garden State Parkway). I haven't been there in a couple of years, since I live down the shore. They weren't too bad then; don't know about now. I just recently picked up some new equipment online. I now usually just scavenge the net for the best deals. This hobby has a whole lot more potential thanks to the internet.
there are 2 spots in NYC i go to: heres the info...
Brooklyn Homebrew 718 369 0776
163 8th st. Brooklyn NY 11215
take the F or R train to 4th avenue 9th street and walk down to 3rd avenue and 8th street, it’s right up 8th off the corner
Hydroponic Garden Center 718 762 8880
14649 Horace Harding Expwy, Flushing NY 11367
Driving - take the LIE to exit 24, it’s on the west bound side visible from the LIE near that exit
+1 on Brooklyn Homebrew - easily accessible from the M and R trains if you're coming from Manhattan and their selection of grains and hops is getting better all the time.
