Yep that's right Elrick! Even if the factory is on schedule and ships by the end of June, it would still take time for sea mail from China to NY and then for me to test, inspect, and ship keyboard by keyboard for 207 keyboards.
Sixty and bocah there was interest in a NYC keyboard meetup but I haven't seen much activity recently on the thread. I'm open to a meetup in Manhattan. Right now the best indication of the F62/F77 quality is to take a look and listen to the 2160p UHD video I posted on YouTube in January. It's high resolution and the sound is clear so each viewer can draw their own conclusions about the prototype sound. The prototypes sound good but I am confident that the production units will be even better!
Why reviews should be taken with a grain of salt: I am hoping to loan out review units once the early bird batch arrives from China, but please keep in mind that every Model F keyboard in my own experience has a unique sound and feel, meaning a reviewer's sample Model F has little chance of matching the sound of another original Model F or of one of these reproductions (the repro's should sound similar to each other given they are all new and from the same early bird manufacturing batch). Given that, many a reviewer will certainly say something like "The sound is not the same as my original Model F." Even the thickness of the inner foam and its state (disintegrating older foam or replacement newer foam) plays a role in the reverberation (thicker foam in my experience makes the keyboard quieter and less reverberant/musical). Two AT's in my collection sound different from each other and from an XT. Two of my F77s sound different from each other and other F's. My F107s sound different than my F122s. Even one of my 1985 F122s sounds different from my 6110344 from mid-1984. And it's not just the sound - the state and type of springs also plays a factor in the typing feel/experience - a long time Model F user may prefer the worn down springs in his original F because of the reduced actuation force, compared to a new F (my new F's take some time to break the springs in so that they are even smoother). Maybe a reviewer prefers quieter keyboards or keyboards at a $100 price point, which would rule out a new Model F.
