Well, I checked the Nikon service page tonight and found my D70 needing yet another B2 repair.  From their site, a B2 repair is:

Moderate Repair : Major Parts Replaced

That makes three B2 repairs on this camera. While I’m very happy that Nikon is taking care of me once again, I wonder how long before I get a B2 repair needed that isn’t a complimentary fix.  I guess I’ll cross my fingers and hope for the best.
