I found a new source for puzzles:

http://www.opensky.ca/~jdhildeb/software/sudokugen/

However, this one has me stuck.
Code:
Puzzle: New Puzzle #69

| . . . | . . . | 5 . . |

Note: when I opened this thread I saw Danny's reply and now I don't. The only thing I can think of is that I accidentally deleted it, for which I'm sorry.

Marty: I deleted it because I wanted to replace it with a fresh solution.

Thanks, that makes me feel better.

Looking at the implications of the 46 UR in boxes 69: in the roof cells, one of them must be a 3 or the other one a 1. Either sets r1c1=4 and r3c5=1 and that solves it.
