The G-Shock GA2110ET-8A, which was thought to have been sold out in the U.S., is currently available again at Gshock.com for $110 (now sold out).
It is also available at Zales and Jared (with shipping limited to the U.S. only). (Update: It is now available at Reeds again. It is still available at Tillys.)
According to G-Shock Japan, this model is no longer in production. This may be the last chance to get it at list price, as most other retailers already released it and sold out their stocks.
