New ereader: suggestions?

Hi

I'm looking for a new ereader and pocketbook seems to match my criteria (readium lcp compatibility..)
What model do you suggest?
So far I came to these (partial) conclusions
Color models seem not completely "mature"
Hd3 seems a nice choice, but reliability doesn't seem its strongest point

I'd also like to read some pdf documents (zooming should be "fast")

Thanks
