I guess it depends on several things.
Where your job is, and how close you want to be to it.
Downtown can offer lots of nice things, though living in raleigh in general is more expensive. North Raleigh is a completely different world than downtown. Morrisville and Cary are right next to the airport and touching raleigh border, so no impossible to live there and commute, i've friends who do that.
One suggestion would to get a place near one of the lakes, they provide nice scenery to go running, and if you don't, it doesn't take long to get there. I'm trying to think of other things, but can't.. if you've got any other questions, i've lived in raleigh for 16 years, just send me a message
