Besides
Dawn of Defiance, there are lots of fan-made adventures that are, IMHO, just as good as the official ones.
If you're the creative type, who would like to start with just an "adventure seed" and develop the story yourself, I recommend the official "Wizards of the Coast Random Star Wars Adventure Seed Generator." If you know how to use the Wayback Machine to view old URLs that have since disappeared, the WotC Random Star Wars Adventure Seed Generator was once located
here. Otherwise, I had the foresight, fortunately, of distilling it to a bunch of dice-rollable charts, which I've recently converted from the original Word file into a .pdf. Unfortunately, I lost it somehow, so if you happen to have a copy, please let me know and we can link to it.
Also, using any adventure seed ideas, combined with
Saurstaulk and Jindy's "Big Book of Archetypes" .pdf (or Jonathan "Donovan Morningfire" Stevens' "Big List of Assorted NPCs") and the "All-Purpose" Saga Edition Stats Sourcebook in my sig for tons of pregenerated stats for NPCs, vehicles, adversaries, etc., give you all you'll ever really need to run a Saga Edition Star Wars game instantaneously (besides the Core Rulebook, of course).
Lastly, Engine Publishing has put out a book entitled Eureka: 501 Adventure Plots to Inspire Game Masters. This 300+ page .pdf, available also as a print book, is NOT simply a compilation of adventure seeds; it is a compilation of fully developed plots for any genre of play. Nearly all of the plots can be used as they are for Star Wars, and the remaining can be used as well with a little tweaking. If you buy the print version, you get the .pdf for free. This book is incredibly awesome and a fun read.
If you prefer to have someone else do all the prep work for you, then you have lots of options. Several fan-made adventures can be found on these forums, and both Prom and I have been collecting them on our MediaFire accounts. You can find the link to those in our sigs. (
Here's my Adventures subfolder on MediaFire) You can also find a few Saga adventures at the D20 Radio downloads page, although I don't believe they have anything that Prom and I don't have.
Also, I understand that you might also consider PMing
Donovan Morningfire. I don't know how often he checks out these boards, but he apparently has a series of Rebellion Era adventures, originally done for cons. You may have more success reaching him at the d20radio.com forums.
