Speaking for the TIE Pilot costume, while his helmet is screen accurate, the chestbox for the most part did not make it to the screen. The biggest problem with the SDS products is the extreme prices. I suggest you contact the Detachments for the costumes you wish to create for details on providers.

Like Targ stated.....SDS has issues that you need to be aware of. That being said.....There ARE Other options out there . One of the current Tk's on here SHOULD be sending you a PM soon to fill you in on the details . If not.......Post back here soon .
