Was just surfing Banggood’s page and found this deal. Ends today.
Astrolux S3 : $17.99
Apparently, the deals been running since Xmas.
Yes it has. 
I bought one, and frankly i think it’s not worth a lot more than $18.
You can use points to reduce the price further. I ordered one and got it down to $14.99 with 300 points. Should be getting it this week.
I really hate the low runtimes of a 14500 but the good parts are easy to use in a 18650 light
I may order it for the tail, led and driver combo, thanks!
It’s a cute little thrower though.
Maybe put in a SK68 driver so you can also run NiMH if you’re gonna take it apart anyway.
You can get the tailswitch board here too:

It’s only $1.31 at the moment.
Great thanks Jerommel ordered one!
