Seen far better craftmanship, actually. You can also buy a new of the one I spent most time with, the Zeiss Favorit 70 . It is a modified Italian Prevost 70, with a bit harder steel and some improved mechanics. No DP70 qualities, but well maintained it ran beautifully and silent with a minimum of film damage. I ve run more than 1000 shows on some movies and returned prints almost as new.
Weakest points are the sound here too.
No really good sound without certain local cutomization. Never seen it live, though.
