I sincerely apologize for the long delay and lack of updates. I was forced to spend quite a lot of energy on another project which ran into a number of unforeseen difficulties. As of last week, most of these issues are now solved.
I assure all backers I am committed to shipping RGGBer as soon as I can. These is no possibility of giving up nor any decision changes. In the past few months, I have received lots of messages from people interested in a RGGBer kit. I am motivated by this and will go on to maintain my project.
Manufacture will be relaunched this September, with hopefully a shipping date by this October. Again, my apologies for this set-back.
