Should I build them

Dave,
It looks like a real quality piece.
The rest of you guys:
I need to say something here.
Dave has a business that not only fills an incredible need, but keeps our passion alive. One of the things that most people in our hobby dont consider is the cost of the time for R&D. Its the profit from the existing products that lets people like Dave develop the future products that solve our problems.
The fact that he is willing to give our small group a 10% discount is a real bonus.
For example, I need frame connectors. I have more than enough time and skill to put together a template and cut the materials needed to make the connectors. However is it worth that time to do so rather than just ordering them from Dave? Time will tell.
I know the quality that comes out of his shop, for me to develop the same ability to build the front mounting points would take way too much time in research to justify that path.
What a part is worth is determined by what people are willing to pay.
I dont need the front end part but considering the complexity of the part it seems like a very fair price.
Just my .02
Andrew
