Tempest Feud (a great adventure, by the way) is the only published adventure for any of the 3 d20 Star Wars systems unfortunately.
Your other choices would be any number of the adventures published by West End Games - virtually all of which take place in the Rebellion era. Most of these can be had for pretty cheap online, and there are tons of them. My favorite was "Operation: Elrood."
Here is a link to all of the WEG published adventures (and supplements), each with a link to Amazon, where you can buy most used for quite cheap.
2nd Edition Adventures - Star Wars - D6 Roleplaying - West End Games - Wayne's World of Books - Info & Sources
Next up, the Saga Edition books
Scum and Villainy and
Galaxy at War each contain several mini-adventures and one full-length adventure. Plus they're really great books!
Additionally, if you search through Wizard's Star Wars RPG web archives, they've released a number of free adventures online (but not for several years), many of which are Rebellion era, but most of which are fairly short.
Lastly, there is, of course, the 10-part adventure path being released for free on Wizard's website - Dawn of Defiance. It takes place in the Dark Times, before the Rebellion, but an industrious GM can change the era fairly easily. It is designed to take characters from 1-20th level.
Hope this helps!
