VPixx sells a "CRT replacement" monitor that competes in that niche; it also has a bunch of TTL lines and other research-friendly features. It's very nice, but also pricy. I know one of them says "affordable", but it's by comparison. https://vpixx.com/our-products/crt-replacement/

Otherwise, there are a lot of threads like this where labs characterize stuff they've bought: http://visionscience.com/pipermail/visionlist_visionscience....
