Seem like an awfully simple piece, yet ones I have found have been close to 100 bucks. Can anyone point me to a fabber that has them at a reasonable price?

check out Spohn!

I bought these. Nice parts.

I think someone posted plans for them a while back. might search for those if you want to make them yourself.

I made a set and they are not quite as simple as they would seem. The Sphon package is a great deal.

These took about 6 hours of flat out work and $20 worth of material to build. Buy the sphon's
