I was a little hesitant to do my own at first. Then of course the realization hits that I assembled the dang thing, why not do it??!!.
No alignment shop out there will know your Goblin as well as you do. And besides, you already have all the proper sockets and wrenches.
I HIGHLY suggest everyone uses the above DIY links in Kyle's post and at least attempt to do the alignment themselves. Once you do it, you will not be nearly as intimidated. And the few odd tools you need are not very expensive - digital angle finder, good straight edge, two identical tape measures. And then, if you still question yourself, have a shop check your work.
