Three sets of pics from three auctions. First set (SN 1145) via this auction, second via this auction, and third via this auction. There's a fourth listed here (pics previously captured here).  Click through to see what each is going for and remember you can search the archives for DX1 auction to what others have gone for.

DX1s are an interesting beast.  There is no doubt they are extremely powerful synths and the pinnacle of the DX line, but their 6-OP FM sound engines are available in other forms.  Aside from the obvious DX-7, DX-200 and Native Instruments FM-7, there is also the  FS1R which is 8-Op FM plus Formant synthesis.
