I understand this question has been asked several times but I couldn't really find any suggestions leaning towards my criteria first off some of these e-readers can be expensive if possible I would like to get it around 100$ to 150$ next i don't want a lit screen I want one of those ink screens like the kindle I would just get that one if it weren't for the fact it does not support SD cards and they tend to be large files they wouldn't all possibly fit on the 3GB storage it has I do not mind size and i understand that it is recommended to be at least 9 inches for them to be easily readable which is why i need it to be compatible with PDF as well as a zooming feature

so really I need it within this criteria

1 SD card or Micro SD supported
2 Ink screened instead of lit
3 PDF compatible
4 Zooming feature

and if there's anything else I am missing to be able to read these things extra help would be appreciated so if you please could suggest what is available like that and if its within that price range that would be great
