The case is different as you may have noticed. When you buy the units new, the 76CSX comes with a 128 MB microSD card whereas the 60CSX has a 64 MB card. The 60CSX includes a belt clip and the 76CSX does not have this as an accessory. The display is exactly the same on both
units and the buttons are very similar.
One more small difference, the 60CSX currently has a $50 rebate offer available.
