When I hear excuses about how some diagnostic test is expensive because the machines are expensive I think of airplanes and rental cars.<p>So you say your ten year old ultrasound costs $50k? I can rent a $50k automobile for $150 a day, not for just ten minutes. And rent a space on a 120 million dollar airplane for a few hundred. And seriously, mom was an accountant. The capital cost of a $50,000 ultrasound machine is about $20&#x2F;day.<p>Meanwhile I have about $50,000 worth of test equipment sitting in my office. I&#x27;d never think of charging a customer a $2500 spectrum analyzer fee. Or a $400 oscilloscope diagnostic fee.<p>Please.
