Replying to Jigs?

I have been looking for a Marker Jig for a long time and can not find one... I'm going to ask my shop if they can sell me one or get me one. If I can't then I'm thinking about using paper jigs for the future because $75 to mount a pair of bindings is too expensive and I would like to learn how to fix everything on my skis so I don't have to rely on a shop.

Would like thoughts on this topic...
and if anyone knows where I can get a marker jig...
