Not as difficult as the previous puzzle. After you get past all of the basics, there is a single-stepper solution.

Code:

+-----------------------+
| . . . | 2 . 5 | . 1 . |
| . . . | . . 6 | . . 2 |
| . . 4 | . 9 . | . . . |
|-------+-------+-------|
| 4 . . | . . . | . 9 1 |
| . . 5 | . . 4 | 7 . . |
| 9 7 . | . 3 8 | . 4 5 |
|-------+-------+-------|
| . . . | . 5 . | . . . |
| 7 . . | 6 . 3 | . . 4 |
| . 4 . | 7 . 1 | . 8 9 |
+-----------------------+

# 59 eliminations remain

r35c12 <12> UR Type 2.2233 <> 8 r4c23,r5c9 -or-
r35c12 <12> UR Type 3.2233 <> various -or-
r35c12 <12> UR Type 4.2233 <> 2 r5c12

Since the fourth puzzle is more difficult than the first three, I'm not going to post it.
