Which SkyBox to get?

I have been using an Eagle Linux box for a little while.

I don't do anything exciting with it, just watch TV.

I am thinking of getting a HD box and have come across these SkyBoxes.

Can any of you please give me a basic difference between the range ?

PVR is nice to have but unless it actually works as advertised, I would probably pull the rest of my hair out.

Looking for a decent quality picture.

Any help would be great

Thanks

Paul
