Budget ultrawide monitor > 29" for macbook air?

I am setting up a docking station for my Macbook Air and would like to pair it with a budget monitor for it. I will only be using it for school but need it to look visually appealing since it will be located in the downstairs office area. Any recommendations?

$200 budget btw...

The cheapest new 29"+ 21:9 monitor on Newegg is $249.

Clearing the size requirement turned up a 25" 2560x1080 display for $179.

You might be able to find something that hits your pricepoint on sale in 2 or 3 months; otherwise it looks like your reach is exceeding your budget.
