My first purchase outside of the core set was Imperial Aces. I saw someone run a Turr Phennir (not in Imp Aces, I know, but I didn't know then
) and was entranced enough to go buy some Interceptors. In fact, I got Imp Aces while my core set was in the mail so I couldn't even use it without borrowing all the pieces from others.
I loved the Interceptor well before I started playing X-Wing, and one look at its amazing maneuverability made me fall in love with the Ints as a game piece too, so you could say my purchase was a bit of both
