What set is the cornerstone to your Lego investing?

Just interested in seeing which Lego set are people relying on most to make them some money. I had been sitting on a few Death Stars (like most people I think) but once I got right into investing I looked at other sets. I have 5 SSDs, but the key to my collection really is my 25 Harry Potter Diagon Alley sets. They are the set I have the most capital currently invested in, and also that take up a fair chunk of space. A significant jump in these and I will be smiling a lot. What is the key set to your Lego investment strategy?
