best way into D.C. ?

Hi all...

I'm planning on flying down to D.C. from northern NJ in a couple of weeks,
and was wondering which airport down there is the best these days? I know
College Park is the most ideal, but unfortunately it's still not accessible
by transient aircraft. Basically, I need the closest airport that has either
a cab or access to public transportation to get into central D.C. I've flown
into Dulles once before, and don't plan on repeating that harrowing
adventure again (the controller that day was just not on his game at all).

Any advice much appreciated! Thanks!
