Ahh..I got you guys now. Sorry, I wasn't quite getting all the details. All I could think of was my ebay experience were as the immediate seller I felt the need to assume full responsibility even though in the back of my mind I was peeved about the person who sold us the DVDs (I just figured...that's not MY buyers problem, I'll take care of this). This example is a little different since you guys were up front and had some prior communication.

Anyhow, you guys might try Laing. They are after all the ones who made the faulty pump. I suspect many of the pumps get to them that are RMAs anyhow.
