It's more then 250 dollars but I love my galaxy note 10.1 2014 edition. Got it refurbished in a groupon buy for about 350 and it works perfectly. The digitizer is wacom and the display is amazing.
I have the 12.2 edition which costs way more than the price range of the OP but it's such a fantastic experience. I use it for everything but coding. I tried a Wacom pad and pen with my desktop but I really disliked it. I much prefer seeing what I write and myself writing it at the same time. My brain didn't like the disconnect of looking at a monitor while drawing on a pad. It made my handwriting much worse.
