There are many who prefer and like the blue Excalibur over the Excalibur 2.
I saw one recently on craigslist that the person was asking $475 and have seen some go for close to the same price on eBay. I remember one time there was a guy from Canada that had an Excalibur 800 new in the box that went for around $450. I had it marked to bid but didn't get home in time.
As a side note, I was looking at eBay the other night where one person had a Excalibur 1000 listed. A few bid the thing up to over $1000.
But, yes, it's an excellent machine. If you buy it you won't regret it.
