Voyager keypad construction

[Zac Bruce]

I'm wondering if there is a difference in the way the keypads were constructed on the original USA made voyagers and later 12c/15c LE? I have a very worn out USA 12c and the keys feel a bit "squishy" and maybe have less travel than the newer models. The bottom half of the enter key does not move at all or give any tactile feedback when pressed but does register. The newer keys have a much more tactile/clicky feel and sound, which I really like. I'm wondering if it's just that my 12c is very worn out. I have the chance to buy a "new" USA made 12C but worry that I might not like the keypad.

Thanks all.
