Market for used BPC NTSC TV sets in 3rd world?

[radiotvnut]

There is a group of Mexicans that hit the local TV shops for dud TV's; and, have been doing it for years. I was told that they are taking them back to Mexico, fixing them, and making a killing on the used market. According to my friend at one of the TV shops; they are getting pickier about what they will take. They used to take almost anything, unless it was really old. Now, they only want TV's not over 5 years old and they must be clean and carry a name brand. He said he's gotten as much as $50 for 36" sets and he also said they would pay good money for flat panel sets.
