Good suggestion matonanjin2.

I was going to suggest Hal Leonard myself earlier. I have a couple of their publications including this and this, the latter being the spiral bound hard copy edition with interactive online audio tutorials (used to be a CD, now digital access).

To the OP, for guitar, go here, select Songbooks from the menu under Guitar Bass Folk Instruments, and in the drop-down sub-menu you'd be hard pressed to not find something [u]at a preferred level to suit[/u] to appease the appetite. Edit: PS. That last link works best in a desktop browser. For some reason, it doesn't present accurately at the same sub-menu within the same browser on an Andriod tablet or phone.
