Have you looked at the threads in our equipment review section for the Conaxsat Trio and the Visionsat IV200?
Both sound pretty good, and seem do what you ask for.
I think the latter is pretty much the same as the CS7000, but without the internal flash buffer.

I'm sure both reviewers will help you out with any particular points, if they aren't covered in the reviews.

I've decided to put the IV200 on my Xmas list.
We'll see how I feel once Xmas is here.
