I've been hunting around E-bay for a similar setup. So far I've just got the levers, paid $30 and they're new. From what I've seen a used set(F&R) of calipers seems to go for $40-50+shipping. So I'd say that price is fair. Might not be the best deal you'll ever find, but it's a good price with a lot less looking effort.
That is definitely a decent price. I got that same deal from Pricepoint for $69.98 last year but prices go up. I've been blown away imperssed with the braking from the set but to each his own. On the outside chance of saving $5-$10 (MAYBE) from eBay, it's easier to order from PP and call it a day. Better than messing with two auctions and the hassles associated with that. But again, that's your call..
The ones from Blueskycycling.com are OEM parts, if that matters to you. It didn't matter to me at that price. Due to my lack of confidence in being able to remove the grips in one piece, I also used the brake upgrade as an opportunity to upgrade to a set of ODI grips .
