I've seen a few members post pix in the gallery of glass percolators, the like of which may have come from old vintage colonic units. while i'm guessing that these were ebay or yard sale finds, i wonder if there are any modern suppliers of these items? it'd be nice to have something made of glass or even hard plastic as it'd be very easy to keep clean and so not subject to mold or bacterial contamination. i do have a stainless steel enema can, but would love to add a glass vessel to my collection. any hints?
