Has Anyone Had Success on a Treadclimber?

At the moment, I'm outdoors often, exercising and completing triathlons as it's peak season. Yet I'm looking now to buy a treadclimber for when the weather gets colder. My logic is the deals are better in the summer then the fall/winter, but not sure if that's true.

I've read some reviews and comparisons online, example: http://www.fitrated.com/treadclimbers/

I guess what I'm drawn to most is the cross aerobic workouts, as a triathlete, this is what I enjoy doing most and is what my sport is based on...

Anyone have any luck with the treadclimber? Looking to get some unbiased opinions. Thanks!
