Have two used, unlocked SCT X3 3000 for $250 shipped each. Updated to latest firmware from SCT, load your own custom tune on it and good to go. Can see from pics 100% unlocked. Hit me up with any questions, glad to help.
Both are x3 3000, just the one that says x3 on front is an older x3 and the other one is a newer model. Both have the same internals though as I updated em to latest firmware version. And the one that says x3 on front is sold.
