i happened to stumble upon a FB add claiming to pay top dollar for converters. i sent message and immediatly got a quote. today a guy came to grab them. younger kid in a nice van, nice professional attire, money bag, reciept give.
paid 100$ each for van converters, i had 4.
he said he and his brother use to work out of state at one of the processing plants, they do partial processing here and then send out material. they try to pay the best $$ around, and are doing well at it.
