You can find a decent one in Fairfax County for $1600 (if you require lots of space like we do). You just have to spend a few weekends with realtors looking around everywhere. There's alot of shitholes that these people are trying to rent out for $15-1800 a month.
Go see Mary Brown at Long & Foster. She's a really sweet older lady that helped us find our house. She's mad cool and does whatever she can to help you.
