I would say that it largely depends on what you're paying for. If you getting a couple of maps or something it should be free, or in the 5-10 dollar range... If you're getting a whole new campaign or something with over 5 hours of solo play time, I don't think paying more than that is unrealistic.
It would also depend on the quality of the product too.
I don't think you can say what price is acceptable for DLC because it's way too big of a question, how much DLC are we talking about? Most games don't charge for patches and maintenance corrections etc, but if you're paying for new content that wasn't available at the release date, I would say the fairness of the price depends on the product...
Not all DLC is created equally, and not all games are created equally.
I would say paying 60 bucks for essentially the same Madden NFL game you played last year with new rosters is probably a bigger rip-off than DLC you can come up with (including horse armor).
