In my opinion D311's are difficult, but they are by no means rare . In fact, quite a few have popped up on Ebay and other places in the past few months. Having collected a few here and there, it's my experience that D310's are the tougher of the two to find. Maybe there's just fewer available because more people are collecting them now then in the past?
