Looking at the kits, I wonder if they've heard of 65% keyboards. They're not really giving us any options for the right hand column above the right arrow. I realize the ~` / Delete / PgUp / PgDn I prefer isn't as common as Home/PgUp/PgDn/End, but it doesn't look like those kits allow for either one. If the navigation keys in the modifiers kit have their rows labelled correctly, then the keys that should be R2 (Del, End, Page Down) are R1, which seems weird. Hopefully that's just a bad picture.
