fanficauthors.net has some. I think Jeconais had a good Hannah one, and a good Padma one. Maybe a good Susan one as well, I forget. The others have done good work as well.
Ficwad has some good lemons, if you search under the character names, although those are mostly along the lnes of harems, and I'm not sure if you count that as a pairing, or even if it's the type of fic you're looking for.
Luna is my preference, just because she's so delightfully batty. At this point she's more or less the only canon character I still like, now that Tonks was depressing all through the last book.
Honestly, at this point I'm only waiting for the last book out of some sort of sense of closure. I started, so I'll finish - that kind of thing.
I'm still undecided about going to the movie, although it's supposed to be quite good. I'm just not sure if I can take two hours of Daniel Radcliff again.
My love of the fandom itself fades in and out over time, nowadays I find that the best fics come from those who have the guts to completely strip down the universe to it's bare essentials, and start anew - usually making a whole lot more sense as they do so.
