These do come up on Ebay regularly. I got one for about $100 that was like new. They are made by Britax. We also bought a Britax (non-porsche) for my wife's car. It goes in the backseat so we didn't need to worry about the airbag deactivation but it was exactly the same as the Porsche seat less the airbag clip. If you could find just the clip you could go with the non-Porsche seat but either way you need the deactivation bar. It needs to be programmed by a Porsche dealer. They wanted $200 for this service.
