How am I going to get rich if I give "a good price"
Seriously, it is too soon to talk price. It will be competitive.
From the front it will look no different. Some modification of the back of the case will be necessary and I need to explore the best internal mounting solution. Right now it fits into the current internal mechanism holder after removing all mechanical parts. A bit awkward my first try. I will work on this aspect. Hopefully, I can show photos of the internal circuit soon. All my questions are not yet answered but I am pretty excited about being able to offer this option soon.
