Instant Legacy offers repair and restoration services for all SX-70/Sonar/SLR680 models. 
We do not currently offer repair services for 600 and Spectra cameras. 

Instant Legacy can modify your SX-70 to shoot 600 film which is cheaper, easier to find locally (Target, Best Buy), and makes great pictures indoors and in low light.    We also offer custom leather skins and a variety of shutter button colors.
$45 for SX-70s
$65 for Sonar models

We are working on new and special accessories to improve the usability, affordability, functionality of your vintage Polaroid camera.   Stay tuned for updates.
