Bowflex Treadclimber--do you have one?

MIM49

Any one have one? Is it really better than an elliptical (burns more calories?) Most posts seem to compare it to a treadmill. I am more interested in how it compares to an elliptical. Also I have heard the treadclimber requires some coordination to use (sort of like patting your head and rubbing your tummy kind of coordination) True?
