Anyone have a F75 10" elliptical concentric coil?

I am wanting to give one of these a try but I don't want to spend the money they are wanting for a new one due to the fact that it may not be that great in my soil. And then I'll never get close to the price I paid for a new one if I decide to get rid of it. So if you have one laying around collecting dust let me know what you want for it. Thanks Morgan

Or if you have one you wouldn't mind sending me to test out I'd appreciate that too! I'd be willing to pay shipping from you then back to you.

No longer looking for one.
