HED3 / HED 3 questions

Cool, thanks. I've only seen them go for 650-750 pounds, 2008/2009 edition. Older sets are found for 400-500. I don't have much use for a freewheel/cassette back, though. :-)

But, what'd you say? I was thinking in the lines of 250~ pounds -- fair?

None of them are perfectly true, due to the way they are manufactured.
Regarding value, newness = +, tub = - . Seen pairs of tubs (f+road rear) go on tri forums for about 490, can't remember how old they were though.
Don't take it for a test ride, you'll hear the nice whooshing noise and then you'll have to buy it.
