I looked at the link you provided. It seemed a little shaky to me. Not to say that he does not have this lexicon. I am sure he does. I got a little wary, when I saw that he was trying to tell us that it is was worth $750. And then trying to tell us that he has got it down to $47, "for us today." I do not mind being sold by a salesman, I usually can see right through them anyway. If you have $47 to lose and you are not worried about it that much, I would give it a go. But only have seven or so lexicons to sell, well, that too is a little weird. I would be selling those things left and right as much as I could, why only a few? Maybe marketing ploy. That is what life is today anyway. One big marketing ploy!!
Maybe, if you have the time and you do decide to get this lexicon. Maybe you can tell us about it, did it work?
