So I would classify you as a sane builder :). In my very early days, I had exactly the same thought of building a generic cockpit and in fact, all I thought I wanted were a few switches here & there so that I could minimize the use of the mouse. But then... somewhere along the way, I decided I had to have a better throttle than the one that came with CH yoke.
I literally started with 2 sticks of wood and I have no idea how that evolved into a reasonably accurate 737 throttle replica. The only explanation that I can think of is 'the disease'. I was infected, as many people here are, and to my knowledge, there are no rehab facilities available yet for that disease.
Good for you about sticking with a generic cockpit. I'm 100% sure that you enjoy flying it every bit as much as anyone with a 'real' flight deck and maybe even more since the real cockpit types are always trying for more 'realism' it seems and getting less flying time in the process (assuming of course that the love of flying is the only motivation for building).
