Portable Tablet for Drawing and Writing?

Hello, I'm looking for a tablet that I'd mostly be using for drawing (so it has to include a pen, which isn't just a tacked-on feature but is actually smooth and pleasant to use with nice pressure points) and writing (I'd buy a wireless keyboard). I'm looking for something that is hopefully under £400, completely portable (not a pen display), and is big enough to be comfortable to draw on but small enough to fit in a bag easily for travel. Android compatible, so I can use Krita, as that is my most preferred software. I won't be using it for anything else, just hobbies, so colour correction, audio, and screen quality are no concerns of mine.

Anybody got any recommendations for tablets? All the ones I keep finding either have reviews with nobody using the pen or reviews that mention lag or jitteriness, and I think that would actually drive me insane lmao. Thank you for any help!
