Anybody using Rocket ELT?

I'm thinking of picking up a lower priced 5.1 speaker package for a 12'x12' room, with a large opening behind my seat into another 12'x8' space. I happened to see where several users here have spoken highly of the Onix Rockets, so I went to av123.com to take a look. While there I see that they have the Rocket Extremely Luscious Theater (ELT) system offered for $699, which is in the price range that I am considering. My question is "does anybody have this system and can offer a review?" If not, how about some recommendations for other 5.1 speaker packages in the sub $750 range. Thanks in advance for any suggestions.
