Ugh. How I would've loved to see TWOK for the first time in the theater. Unfortunately I was born two years after its release.
Ouch... Instant "make-me-aware-of-every-aching-joint-in-my-body" oldness alert.
Aye... those were the days...
Have you considered making a replica of the phaser they used for TSFS? I just got my replica (ok... toy) in the mail, and I love how well it manages to harken back to the TOS era, and yet brings that classy older version into the present (albeit a present over thirty years ago). Ow, there go my joints again.

I think they made new communicators for TSFS too, but they were even more similar to their TOS style counterparts than any other prop.
