I agree if I like what I see I go to Idp then you tube. After that I read up on the rules and see If I it's a decent deal. After that I buy it. If I don't like it I sell it. I've been thru 40 machines. Along the way you learn a lot and bring back things to life. I say don't go by the top 100 at all. That's more a a me too listing. If frankly top dog likes it everyone else seems to also. I started with solid state and now I only like woodrails from 1950 to 1960. That's it. Most people can't be bothered. So it's really up to you.
