There are some great options in the Buckhead / Broohaven area. If you think that a townhome is the best fit for your lifestyle, I would recommend looking at established townhome communities, such as Fernwood Park, 2600 Peachtree, or Brookhaven Glen. There were several developments that went under when the market crashed in 2008 so they are still a little shaky and probably not a good investment right now.
There are some other townhome developments with a strong HOA and a true sense of community that are less than 15 minutes from the heart of Buckhead. I just helped a good friend buy a townhome at One River Place and we were truly impressed.
