Here are two that I did myself Chris.

I wound up painting the second one to match the first... I'm doing my '07 PA buck the same way. I just finished skinning the head, removed the C1 vertrebrae (that was still attached) - got the bottom jaw cut out clean... Now for the dirty work (boiling). Give me a holler and I can walk you through it.

Definitely not hard, but you'll need4 things:
[ol][*]A lot of spare time[*]A strong stomach[*]An electric roaster[*]A place to do it outside the house (boiling brain smells horrible).[/ol]Like you said... A whole lot cheaper than a shoulder mount - look pretty cool too.
