I believe if you look at that way, you pay for every thing you do. I could say, or to justify my feelings, my time is worth $100. 00 per hr, so have someone else do it for me. But if I break down on the road my own hands might get me going again. My understanding, The kit from Cummins is around $50. 00-60. 00 complet pluse shipping. Is't this site about doing stuff your self? I believe that experience is what life is about, and teaching if possable is pricless.

I am not intending to start a battle here, just trying to make a point. Get your hands dirty.
