i used buy all my pieces at a great head shop in cincinnati while i was in college - near uc in clifton. don't know if thats too far for you. i can't remember the name but if your interested, let me know. i can find out.
thats a little far for me. isint there a place in yellow springs? i would like the name/adress of that shop in cinci though.
By far the best glass I've seen (way better than Clifton) is in Caesar's Creek flea market, at a shop called Mad Hatter.
