187, 217 (Three of these!), 209, 213 are the only duplicates I can think of off the top of my head. I really want another 239 and a bigger 169 (only have the SE) though!
239, 217, 219, 150, 131, 191, 190, 252, 209, 116, 266 and 208.. I usually have 6 sets of brushes, not all MAC but these are most of my MAC ones -- I have onesies of 182 and 131 now!
