Stihl Kombi with a pole saw attachment and a power broom to clean up. I am not sure it will last all of 30 years, but most of trimming is done overhead that is unsafe with a chainsaw. I kick myself every day I didn't get a Kombi when I bought a trimmer a few years ago.
Lets make sure you last 30 years...
