A nice sentiment, but when was the last time you saw a tv repair shop? Even replacement CRT's for vintage arcade games are drying up. The technology to make them will be lost in a few more years, if not already.
The Ms. Pac Man machine at my local movie theater looks weird with an 16:9 LCD panel mounted in the cabinet.
It was a little sad when I saw one of those Sony CRT HD sets sitting on curb destined for the scrap heap a while back.
