i wouldnt buy a piece on-line. you dont knwo what your going to really get, there are certain things u need to look at when buying a piece. like glass quality, and how larrge the hole in the bowl is and if the holes on the piece are actually round and not mishapped, my advice is find a local shop if there isnt one drive to one, bring some weed and break that baby in on the way back. i have drove over 3 hours to a shop in RI and it was worth it.
