Clone question REF HD Reception

[Ravenquest]

Hi there, I am looking at maybe getting a clone as money is beyond tight these days and my old rxr died :/ (have always bough official dmm over the years)

I have been reading about the clone 800, now I am aware about the problems of only being able to use the bootlader it comes with but I am reading about people having lots of problems on hd channels with a lot of breakup and artefacting of the image.

Anyone here using a clone and having these problems?

Thanks.
