The recently released SLA 2nd Edition is much less clunky, trades (Lots of) crunch for a more cinematic approach if you like that kind of thing. There's also a progression in world lore and refinements or redesigns of previous ideas. I like the lore, but still not convinced by the combat, very much like the original I guess.

You could also consider searching for Savage SLA which I believe is still available for download. My team didnt get on with it, but I'm a huge fan of savage worlds so I think it's worth a look.
