Best Dumb (non smart) TV

I am in the market for a new television 42"-55". I am current user of a Sony nsz-gs7 Google TV box. I would like to continue to have my "smart" functions from a box/receiver. I like not being stuck with one platform or system with the purchase of a TV. I can upgrade or change without having to buy a new television.

So what is my best option right now when it comes to a non smart TV?
