Hmm... what side of Atlanta are you considering, and are you considering just the suburbs of "Atlanta" or the surrounding towns also. The Atlanta sprawl really is quite large. I'm guessing you want to be within 30 minutes of the perimeter? Or not? How far from certain things are you looking to be?
The airport, for example, is actually not even IN Atlanta. It is south west in a suburb.
Is there a particular side of the perimeter you would like to be? North of it, nearer the mountains and TN? South of it, so you don't have to drive through it to travel south (relatives living south of Atlanta, for example)? Frequent visits to the coast?
Can you provide more details about what you are looking for? Atlanta and its surrounding area is really, really, large. There's a reason for the old "tri-county" reference... it really does encompass 3 counties. These days, maybe more.
