I also use Songbook. I used Songsheet Generator, but it was not so intuitive. I get the chordpro from Chordie, then in Songbook its as simple as File-Copy form Clipboard, and it's in songbook. Songbook has a display window for seeing it formatted in Songbook display, and an Edit window for editing the file. I tweak it if needed, and save. And if you don't like the key, you can transpose with a click, and when you find a new key you like you can "Save Tranposed" and save it in transposed version. And it prints very well, and give lots of font options and margin options (so I can print offset from the left so I can punch holes in the page, for example).
Songbook is free to try, and I used it off and on for quite a while like that. But when I finally decided it was the program to manage my library, I paid for it and got the registration.
As a worship musician, I have to come up with a fresh variety of music for our congregation. Songbook makes this easy and easy to keep up with. there's even a live performance feature where I get a full-screen display and it automatically scrolls so I don't have to take my hands off the guitar!
