Simply make your own. It is easy to do. The hard part is the stem. You will need a couple tries and a really long drill bit. 3 bits actually. A really long one that is like 1/4" A spade bit that is about 1" and one that is the size of the outside of your stem. Use a VERY hard wood for the bowl. Something like Madrone or Mansanita are very good. Some woods are not good for this. Good rule of thumb is that soft-woods are bad-juju for smoking pipes. Mine is made of desert ironwood and sugar maple for the stem. have enough wood for a few tries. Get some brass wire that is used for Jewlery and spin it into a tight spiral then press it down into the pipe bowl. It will be a non-toxic screen.
Then put it all together, Pack that bowl with some of your best Home-grown and spark that baby up.
