Hi,
I have a nearly new one with a few damaged tubes (3 or so) by the oem fan falling off the shaft, 2 months after I replaced, easily fixed by an aluminum welder. The problem is shipping from Ontario to you would cost too much. I'm keeping it just so I'll never need another one... Murphy's law, you know.
My replacement I found at Advanced Auto Parts for $309 US, couldn't beat that price anywhere.
