I went down this route and wound up with the ACER 27 inch touch screen (10 touch points). It works great (I also got a 23 inch touch for dual monitors). The 23 inch screen was just too small to be precise.
I am now only using the 27 inch model and I love it. (I have another 4K 27 inch NON touch screen as my second monitor). I put the console on the touch and track mode on the NON touch.
I think I paid about $399 for the 27 incher (best buy Holiday sale). You can still pick one up NEW for under $500.
It took me a long time to abandon the MOUSE on the console mode but after a few months, all is well.
