Agree with Mimo. K3 is obsolete now. Even if K3 did exist, CR-1 is FAR superior. Also as for processing, CR-1 and K3 were roughly the same, that's why K3 was made obsolete.
Totally understandable. You just want to be together asap and are so worried about any tiny mistake that might damage that. Try not to fret too much though because remember, when you are together (and you WILL be, no matter how long it takes) it will be forever.
