I love Saga Edition. I have all the WotC d20 SW books. Both from the original release, the Revised rules, and Saga Edition.
Saga Edition is my personal favorite, hands down. It uses a sort of a hybrid system that bridges the gap between 3.5 and 4e. Its a good game. Haven't played it in a long time, though.
My group house ruled a couple of things, but I don't remember all the details.
We made HP static, instead of a die roll. We house ruled action points to work more like 4e action points since we didn't like the notion of a per level resource that required you to level up to regain them. We also house ruled in a recovery mechanic for the encounter powers, so Jedi could recover and reuse some of their encounter oriented force powers mid-battle if they wanted to.
