Nightfall: I wrote off Scarred Lands from my personal choices before I even posted up this topic.
Nightfall really shouldn't be calling out other folk for their ability to sell a setting, I think...
Anyway, if it means anything, one thing that might turn you onto the Scarred Lands again would be the fact that it's currently selling quite inexpensively. Most of the books can be bought for less than half the cover price from White-Wolf.
And unless that does anything to change your mind, I'll say no more on it.
With that said:
Midnight's a dark, depressing setting that, if what you're looking into is, in part, based on what other people are willing to play, you may have some trouble with. It's low magic, which you seem keen on, but the heroes are also on the outs in a world run by evil. I personally think it's great and that it's a setting where being a hero is even more important than in other campaign settings, but it's rather grim and hopeless at times. It also uses its own magic system and pretty much eliminates any D&D class with spells, with only three new classes to replace them.
If you do go for Midnight (and I do recommend it; it's great), I'd wait a bit on it. The current book is 3.0, but a 3.5 book is supposed to be coming out at some point later in the year, I think. Of course, if you're impatient, that does become a bit problematic, but...ah well.
You mentioned Eberron, so I will say that while low-level magic is common, and there's some pretty high fantasy elements, it makes it a point of mentioning how high level magic tends to be rare and that the PC's are the real heroes in the setting. Furthermore, Keith Baker's really dedicated to the setting and spends a great deal amount of time on the Eberron boards over at the Wizards site.
