Where can i find a cheap tablet notebook for note taking, in the uk?

Can be second hand or anything, can’t afford to spend much, upto £200 max.
I was thinking of getting a netbook but i can’t draw diagrams on there can i? It might be all my budget will allow but i thought i’d ask anyway.

I saw Google Android 2.2 from http://www.brandsdargon.com/products/product_26488.htm yesterday...
i don't know if it was the right choice... few of my friends told me this site was good and trusted site but when i searched online i found lot of good and bad review as well.should I trust it or not...

 

every online shopping website have good and bad review,I know some of problems about that.Most of problems occur on the shipping agency,If you can ask their ship by DHL or EMS I think you can trusted it.Our website supply various netbook.you can find some links on my signature.Some of netbook we provide ship by express.
Thanks
