The Underground, Brattleboro VT- Convenient location downtown, average selection, high prices
Phat Stuff, Winchester NH- A little out of the way but very good selection of mid to high end pieces, and reasonable prices, easy to get to from the University and the general tri-state area.
Northern Lights, Enfield CT- Best selection and prices I've ever seen, period. Nothing but smoking products; they are a true head shop.
Vibrations- Enfield, CT- Keep on truckin' down the street to Northern Lights instead. Unless you want to buy a vibrator.
