Tyson's is really congested.
In the McLean, Falls Church, Tyson's area expect like 800-1200 for a decent place. I currently live in Reston and share a 2 bedroom condo that's 1600. Then Reston area is 15-40 minutes from McLean depending on the time you commute to McLean. I also work in McLean and find the commute to be fine. Usually about 20 minutes around 6:30 am. After 7 it jumps to ~30-40 minutes.
Personally I'd recommend Reston or Northern Arlington to live. Tyson's sucks, McLean is really quiet, Arlington has good night life but can be congested, Reston has good night life and is a planned community so the congestion is minimal. Fairfax, Vienna and Oakton get bad congestion as well.
