Shine on You Crazy Diamond

Following on from my previous lockout lines puzzles, here's another one from the broken 159 series that was made a long time back. Please enjoy.

    The Rules:

  • Normal Sudoku rules apply.
  • Broken 159 rules apply: digits in red-shaded cells in column 1 indicate the position of 1 in the corresponding row. The same is true in columns 5 and 9 for 5's and 9's respectively. *All possible red cells are given, so a negative constraint applies.*
  • Lockout lines: digits in diamonds directly connected by a lockout line must differ by 4 or more. Digits on a line must fall strictly outside the range defined by their diamonds.
  • Between lines: digits on a grey line must fall strictly inside the range defined by their endpoints in the circles.

Fun puzzle.. tried to give you a "SUPER DUPER very nice" to counteract the BS rating you already received, but it wouldn't accept it ... *shrug*
