For the 3:2 aspect ratio and 12.3 inch screen, there are only two options - the Plus and Pro, with the Plus being the less exspensive model. There are tons of other Chromebooks, including either Samsung models, that will carry a smaller price tag that either of these models. Most other Chromebooks will not include the built in stylus and will drop the touchscreen.
Check out the Asus Flip ( https://www.bestbuy.com/site/asus-flip-c213sa-2-in-1-11-6-touch-screen-chromebook-intel-celeron-4gb-memory-32gb-emmc-flash-memory-gray-dark-gray/5864604.p?skuId=5864604 ). The one in the link still has a touchscreen and is able to "flip" between tablet and laptop mode just like the Samsung ones.
