Depends what metal you are talking about. I wouldn't differentiate carbon from metal so drastically. Carbon exploding suddenly and without warning is kind of an old wive's tale.
Don't get me wrong--I have the same worry as you but it is as-yet unsubstantiated by any sort of evidence. Thinking scientifically, I see no reason why a carbon component would fail after 7 years unless it had developed stress marks of some kind. Carbon fiber has a far superior fatigue life compared to metals.
I also feel that if it is in good condition, I would trust a deep-dish wheel over a carbon seatpost of the same age. I don't think that I would even trust a new carbon seatpost, actually (mostly because Thomson seatposts exist). Having built wheels myself (though only aluminum), I kind of feel comfortable about the durability of 2.2 inch deep CF rims assuming they pass a thorough visual inspection. If it were an ultra-light weight, low profile design, then I would certainly be more wary.
I was basically wondering if anyone had heard horrible things about this model of AC wheels, but having found that Pez review, they actually seem to be pretty solid. I think I've been beaten to the punch, anyway. I should have been a bit quicker considering the seller was letting them go for $200.
As usual, what was an impulse buy is now turning into me scouring ebay for parts (though the cheapest I am going to be able to get away with is probably 2.5 times the original price, haha).
