50nl: Bad stack off with tiny set?

[DonkeyOnTilt]

I know sets are the nuts at 50nl but I am aware that sometimes they need to be folded. Is this such a spot? Villian seemed solid and had 20.79 / 3.96 / 2.95 stats over 202 hands. He views me as a LAG. If this is standard I apologize for wasting time again.
