looking for denver area head shops

so i've been in denver a year or so now and have only gone to one two pipe shops. one had awesome stuff but was overpriced and the other had decent stuff at a reasonable price. anyways, i'm looking for some quality pipe shops in the denver metro or surrounding areas. specifically places with a good selection of bongs.

anyone have any advice of places to go?

also, i'm not new or anything. i couldn't remember the password for my old username or the email address i was registered with. maybe marijuana does affect the memory
