So confused

Hello

Sorry for the rather generic question that i am sure has been asked a million times, anyway here goes.

I have looked and read all the discussions about the various tablets and i am still non the wiser and a little confused.

Firstly my budget is appox £150

I work in education and would like to utilise all the various apps that i have seen in order to help my students with literacy and numeracy.

It should be robust as it will be used by young children

I want a tablet that connects to the Android market without fafing around if possible.

Screen size is not of major importance but 7" is a minimum.

As larger capacity as possible, i am willing to pay for extra memory

I dont care if it is not a well known brand as long as it is reliable.

Battery life to be as long as possible, i fully understand the limitations.

And finally i don't care where i buy it from.

I would appreciate any advice.

Cheers
