Hi Doug,

Most straps come with a little leather string at one end and this ties around the head of the guitar right where the fretboard ends. Under the strings just behind the nut, that little white plastic strip that the strings rest on by the first fret. You can do this instead of adding another strap button if you want to.
As far as quality goes, I've only bought one strap recently and it was by Harley Davidson, quality leather strap but more of a rock look. Stephy brands look like good quality but I haven't tested one. I would go with what's comfortable for you and take a good look at the stitching, etc. and see if it looks like quality material.
