1/17 update: I've decided to make these in batches of 10. The first batch will hopefully be available by late next week. I'm using the Nyko cable to pair up the Micro link with. It allows for a much cleaner looking cable than hacking the Nintendo one. Price will still be $25. I'll have a photo of the final product early next week.
I will only begin to take orders once I have finished the first batch. I'll be updating the first post with that information when the time comes so keep an eye out next week on this thread if you want one of the first 10.
