Advice needed from Seattle members

I figure Seattle is a little cheaper but not by much. Right now I have a 40 minute commute (35miles) but of course I leave at 4:45am. I am home by 2:15pm though. Airport noise is something to think about. I guess the commuter trains could also be an option for me. How is the commute coming in from the north or northeast? Sounds like the south of the city is like here in DC, terrible. Price range is around 4.
