Newer? That stuff is all old washed up junk here now. There's lots of newer versions of those models still sold today... but cripes.. the 3940/60 are closing in on 40. Even the 50/70 series machines are 25 plus years old. It's not that I'm in the center of the universe for used farm gear either. We get two consignment sales a year with the odd dispersal here and there..
