This is another one I enjoyed very much. I'm not sure my 2nd step was needed since after I played it I noticed a triple in the area.

W on 15, Type 4 on 29, Type 4 on 46, coloring on 8, Type 6 on 37 and coloring on 7


Note to Keith: I encountered the seldom-seen Type 5, but it eliminated nothing.

I have also seen a useless Type 5, once. No one has ever seen useful Type 5 (that makes any eliminations).

So you don't have to go hunting, a Type 5 is a diagonal Type 2.
Code:
+-------------+
|  #   -   -  |
| 12   -  123 |
|  #   -   -  |
+-------------+
| 123  -  12  |
|  -   -   #  |
|  -   -   #  |
+-------------+
None of the cells # can be <3>.
