I think most of them are pretty good. You have Eddie Howard's, Sebastian's Organ Essentials, Mike Lloyd's and Trina Trine's. And with those you the on screen midi board, so even if they dont break something down, you can still learn it (use the pause button). I think the gospel keys organ worship chords was also good. all the chords are spelled out on the screen and they include a chord book, but they only use one key (Db) and they dont give you as many applications where you can use the chords.
So which one is best for you? depends on your skill level, I think Sebastian's Organ Essentials and gospel keys might give the best foundation for organ, but the others were a little "phatter" for the intermediate and advanced musicians.
