I'm surprised more people aren't recommending Pragmatic Bookshelf.

They seem to have great terms for their authors. I guess the only drawback could be that your particular open source book isn't something that fits with their established bookshelf, but it never hurts to ask.

I always preferred the F-23 in Jetfighter II. I was sad to see it passed over in real life.
