Good Morning Alex;
     You might want to check and edit your post. The prices are confusing. An error on the single engine price??
    Type at you later,

  PS to add:
  OK, I'm more awake now?? They are $525 each, or $500 each if you buy both at the same time, correct? I think it was the zeros that had me cross eyed!! Sorry for any confusion. I am going to let a friend of mine know about these.
