Looking for help on choosing a tablet

Hi, a newbie here, looking for advice about which tablet to buy, please. I want a tablet mainly to read PDFs of articles & books. I've looked at ebook readers such as the Kindle, but if a tablet would do the job, then I thought I'd get one, since it would do so much more (I'm not bothered about e-ink). I'm on a budget, so no Apple products for me (and anyway, I like Android).

Here are my basic requirements:

* Price 100-150 Euro
* Able to display PDFS of journal articles & books at readable size.
* Allows annotation of PDFs (highlighting, adding notes &c)
* Easy navigation of PDFs
* Other ebook formats supported (no need for DRM)
* Screen decent size and resolution for reading (say 7 inch min)
* Touch screen & stylus
* Wi-fi
* Web browser
* Word processor
* If possible, front facing camera for video calls
* Decent build quality
* Shipping to Europe (Greece)

Anything beyond this is a bonus.

I'd be very grateful for recommendations as to what to go for. Gpad perhaps?

Thanks in advance for your help.
