Got an EcoHitch for my wife's Subie (Crosstrek). More expensive than what you can find on etrailer. Much less expensive than the factory hitch. Not available for most cars, though. They're a small operation.
It's the only one that was substantially different than everything else on the market. NONE of the others (even the factory hitch) used the bumper cutout, and that was a priority for my wife. The hitch is rated for more weight than the car is rated to tow, so durability hasn't even remotely been a concern. We've had it for about 2 1/2 years now.
We use it with a Kuat NV rack, and have never put more than 2 bikes on it.
