The DX is built sturdier than the SS. Its a different kind of stainless steel that is more durable. I believe I also read that the manufacturing process for the DX is more labor intensive and results in a more durable razor.
I believe that the DX is more designed for use by barbers, whereas the SS is more made for the average person; so its built to different standards and the price reflects that.
