Coax inputs are still as popular as ever, my parents new 60" Sharp has them.

I would go with your 40" choice selection or even a 42". I have a 40" LCD in our bedroom and it works very well. Just be carefull which one you choose as I am seeing more LCD's with shiny screens, not good for glare in bright rooms.
