I found several listings for security monitors and door cams using those flat watchman style CRTs, so similar TV's aren't surprising. I just wish they'd post better pictures of the actual products. In the picture of the watchman clone they didn't even bother to remove all the color from the "on screen" image, but I guess actual screen shots are too much to ask.
Most of those larger sets seem to use the same manual electronic tuning as the discount 5" sets. Some of the larger sets and possibly the 16:9 sets seem to have the same auto tuning as most current sets. That click tuner on one of the 14" sets surprised me though. Someone must have a warehouse full of old click tuners as they can't be cheaper to manufacture.
I'll have to go scrounging through the crappy markets I usually avoid, maybe someone has those 16:9 sets...
