Guess what??
I found 3 GECK!!!
i think its a bug, since mine is 1.02..
during the gameplay i did not accomplish the vault 13 quest but i got the GECK by lockpicking it with 120% lockpick..
but for some reason the voice thing did not appear in the new reno arms shop, and i am unable to complete it, so i headed for the enclave...
after killing the Mr. President and Mr. Horrigan, i get now 2 GECKs.,,,
so i continued playing and finishing the unfinish quest...
but after trying again to find the voice thing in New Reno shops, i found none,
i got angry and killed the arms shop dude with 450 damage with a Bozar.
There it IS! the voice module! i got it and return to the Vault 13 and fixed it, after that i went and ask that deathklaw dude about my stuff..
HE GAVE IT TO ME!!! 3 GECKS!!!!!!
afterwards...when i came back...the deathklaws are killed by Frank Horrigan, who got killed by me already on the oil rig. (strange...)
