Whether you sold one rare set for crazy net profit or flipped +50 of the same set and still counting...which Lego set has been most profitable overall for you?  Total net cash accumulated.  Not including polybags. 

 

I'm only approaching yr 1 in investing so my inventory/transaction history is rather short, so for me it would have to be the Technic Exculsive Crawler (followed by the Hulk Helicarrier Break out which is gaining fast). 

 

Seems like a slow day on the forums (and bored at work haha), curious which sets other people cashed/cashing in on...money makers.  Lets see if there are surprises...             

 

 

Second best sale, 2 Sungnyemuns, bought for around 28$, sold on for 70$, the other for 95$.

I had a similar Architecture experience - bought a NISB Hancock Center for $20, and sold it for $93 the next day. I actually almost didn't list and then thought I would list it on the high end of current eNay sold prices. The next day - poof! Sold overseas through EBay GSP.
