You trying to pull our legs or something? You add to a 2 post thread ... the first asked the same question, the second gave the answer, and then you ask again?

Whilst you'd think an EKG in a Doctor's office should be cheaper since you're not supporting all that overhead, it may not be. Assume the same and then if it's less, you're in luck.
After all, people rarely go around calling doctor's offices to do an "What do you charge for service X?"
