For at least the last 2 York meets, a dealer has had a Blue Comet headed by a 400E (I think with nickel trim) for sale in the Orange Hall, and the price was around $16k. To my knowledge, it hasn't sold. This dealer also has one on ebay, headed by a 390E, for $5900. It's been there a while, and hasn't sold either. Pretty big spread there, and both prices are too high, or they would've sold by now.
