Decent Android tablet under £200?

[itm]

I'm looking a a responsive Android tablet (7/8/10 inch) for less than £200. It'll be permanently located at my bedside (and usually connected to a power source), and will be primarily used for email, web browsing and checking news feeds. Occasional access to iPlayer/Youtube.

I've been using a Nexus 7 (2012) and it's just died. Even before it did, it was getting horribly slow and unresponsive (e.g. I was frequently waiting 15-20 seconds to type after opening a web browser or composing an email), so I'm looking for something to replace it that won't suffer from terrible lag.

Things that are important to me:
- general responsiveness (i.e. no lag when doing the kinds of things described above)
- at least 16Gb storage
- ideally a Micro SD card slot

Things are that not important:
- screen resolution (e.g. 1280 x 800 would be fine)
- battery life (I only use it for 10-15 mins per day. The rest of the time I can leave it on charge).

Does anyone have any recommendations? At the moment I'm considering the Asus Zenpad 8 Z580C and Lenovo tab a10-30. I've had bad experiences with Acer Iconia tablets in the past (serious wifi bugs, generally terrible responsiveness and appalling attitude from support staff), so I'd like to avoid buying Acer again.

I have a bunch of vouchers for Currys, so it would be a bonus if I could buy something from there, but not essential.

TIA for any feedback/suggestions.

What did you end up getting?

For a friend, looking at Lenovo Yoga Tab 10 £170 (or plus version £250).

At first I went for a Fusion5 10.1 inch tablet (model 108), but after returning 2 faulty units I got a refund. Both units would frequently not turn on when I pressed the power button, requiring a hard reboot to revive them. Shame, as the performance was amazing.
I then bought an ex-demo Asus Zenpad 10 Z300C (about £98 including postage). So far I've been extremely happy with it. No lag, and a nice looking unit.
