Just a note I spoke to Jess at Casiosalesandservice today, He said he has several MIRB Frogs. He usually has them at list price but has several and they are going for $ 299 not the lowest price I have seen but they seam to be starting to dry up a little. I called to check on the red G7900 he said he did not think they are released in the USA yet. He said he would check with Casio in New Jersey he can only get GShocks that are released in the USA He has the black G7900 for $79.99 which is lower than amazon currently.
Disclamer I dont work for him but have bought several GShocks from him at his location and through the mail, he has been patient with me while I have agonized over which G to get. He is located in Huntington Beach CA.
