$18.24 (plus an 18650 cell that most people already have) seems pretty good value to me.
You might want to wait until others have reviewed this as DX's specs are often wrong. I just received a drop-in from DX that was listed as being 3.7v-to 4.2v, but arrived being 8.4v. Then the LED actually fell off of the drop-in as I was looking at it.

Urgh.
