Used Precor EFX 576i for sale, ~9 years old and in great condition. We just moved to a new house and have to get rid of this, unfortunately, because there is simply no room for it. As you can see in the pictures, it is partially disassembled w/ minimal reassembly needed. However, you need to come pick it up and it is very heavy (~340 lbs). It will also require a vehicle - as well as at least 2-3 able-bodied people to lift it - that can handle the weight and size of the base (80" x 32" x 49.5"). I can certainly be one of those people if needed.
Here is a link to the video that I followed to disassemble the machine, which can also be referenced for reassembly: https://www.youtube.com/watch?v=UEJOv-LRe7g
