Have you considered RGB modding some of those coax only tvs? If they have RGB mods available you can get the best picture quality possible out of them. Also where you located? My marketplace in NY has loads of people trying to give their tvs away for free or super cheap. These things are heavy. I guess the smaller sets tend to command some cash (and some famous tiny models go for a lot). Possibly try expanding your search radius if you are willing to drive.
