Congrats on an awesome score!
Last year I found my SJP new in the box at a local farm supply store. It had been there on the shelf for over five years. I badgered them as best I could, but only got them down 10% off of retail. It was worth it though. Today it is one of my favorite kettles. And you're right, they are absolutely the coolest camping rig on the planet!
