The Max Keyboards key caps were just on massdrop.
Techkeys.us has a pretty nice Cherry-replica set with translucent legends:MoreShow Image(http://cdn.shopify.com/s/files/1/0218/4886/products/BackLit_1024x1024.jpg?v=1398013030)

Max Keyboards seem to have a decent keyset on their backlit keyboards as well:MoreShow Image(http://www.maxkeyboard.com/images/overview/Blackbird-TKL-KEY-CAPS-920.jpg)

I guess the question is, what other options are there for double shot key caps with translucent legends? Furthermore, what would be the interest for a perhaps more conventional keyset with translucent legends? Chime in and maybe we can start an IC... but something like a DSA Dolch-like keyset with translucent legends might be amazing...
Kinda not exactly what you are asking for but I might bug max keyboards again. I asked them last year if they were going to sell those doubleshot keycaps without the keyboard and they said they were planning on it really soon, maybe it didn't pan out.
Wasn't the cherry legends replica from the gb on gh?
