I'm not going to quote prices on here, but he is very reasonable and will work with your budget if you have one. The best thing to do is email him, which if anyone is interested, pm me.
The horn is angled up so no worries about the tobacco falling out, besides after a bowl is lit and tamped I could probably smoke upside down and not lose much tobacco even out of oe of my billiards. The only tricky thing about the horn is the initial lighting which requires yoy to hold it up high so that the hole is level, but after that just tamp and smoke.
I'm wondering what he charges too.. maybe you could post some rates or contact info for him to us? i'd take his email at any rate if you're still giving it out
