The Set M puzzles can be solved with Basics and Basics+ techniques. I'll identify each puzzle.

Basics : Naked/Hidden Single/Pair/Triple/Quad, Locked Candidate 1/2

Basics+ : Basics, X-Wing, BUG+1

I'd like to know if you found this puzzle worthwhile.

Code:
 +-----------------------+
 | . . . | 2 7 . | . . . |
 | . 7 . | . . 3 | . . . |
 | . . 8 | . 6 . | . . 7 |
 |-------+-------+-------|
 | 2 . . | . 8 1 | . . 6 |
 | 8 . 9 | 7 . . | . 2 . |
 | . 1 . | 6 . . | . 9 3 |
 |-------+-------+-------|

I tried to avoid the obvious Type 1 URs.
