For around £100 you won't do better than a HUDL2 from Tesco.
No it's not an iPad obv. But still decent and very good value for £.
+1 for the HUDL2 from Tesco.
From what you say you do the only real difference will be the smaller screen. It is a similar size to the iPad mini.
I use an iPad Air but my Dad got a HUDL2. I set it up for him and was really impressed with it.
