There are a few different brands to select from... I chose "Green Touch" ($225) due to the good feedback reviews:

It arrived via UPS from Amazon in 4 days. It came packaged in a shipping tube that provides extreme protection from enroute damage. Assembly is simple with the provided screwdriver and takes about a half hour on a clean, flat work surface. This frame is extruded aluminum and all led's and sensors are inside the extrusion. Again, very well protected.
I put it together, plugged it into a USB port, and started using it right away. It works better than my 73 year old fingers do, but practice makes perfect and my touch screening on the desktop is improving. I have found a pencil eraser to be an excellent stylus for setting it up, especially with small icons on the desktop. It really does work very well, especially after calibrating the touch point with Windows 10 settings. Just search for "touch" and you'll find it.
For temporary positioning over the TV, I propped up the bottom of the frame with wood scraps and attached it to the TV frame with "EZ Tack" adhesive clay. This allows fine adjustments for initial testing and calibration without serious glue or hardware. For fine adjustments to the height, use some old playing cards to get it just right.
I'll give it a week of game play, then will report back... over.
