Octane Fitness LateralX LX8000, the same commercial lateral trainer you see in high-end gyms. About $8,500 new. Home-gym use only, clean, everything works.
It moves in 3-D: up/down, forward/back, and side to side. That works your glutes, hips and outer thighs in a way a normal elliptical can't, and it's easy on the knees.
