need source of dried cacti for use in incense, potpouri, other crafts....

i've found a number of sites offering dried cactus flesh for use in potpourri or incense or other such things.....

looking more specifically at T. peruvianus or T. pachanoi.....

i'd really like some info PM-ed to me regarding any suppliers you know of as being legitamite, reliable, speedy, and of good quality. i only want the finest incense

i can go out on a limb here, but i'd just rather not. also, good prices are important as well.

preferably the less white flesh the better. send me some input!
