Normally I'd say that such a price is too high for that bike- but since it has been updated and overhauled, it doesn't look like a bad deal at all.
And if you could talk the guy down, so much the better....but even at full price, a truly "turn-key" bike is worth it.
Only thing: How tall are you? I'm 5'10" and ride a 54cm- but quite frankly, the way that bike is set up (for a bigger rider) I know I'd feel too stretched out on it, with the long stem and set-back seat post.
