Glass etching stencil makers, are there any?

Is there a glass etching sandblaster that you can hook up to your own air compressor? (like the one you may have in your garage)

And, does anyone have any links for kits that you can buy which you can print symbols/pictures/etc on your computer and make stencils that way? Yes, I know, contact paper is just fine, but I’m kind of wanting a permenat stencil for future use. I found a kit that was about 200 bucks, but it is for liquid etching medium only, not sandblasting.
