Zanflare F2 for $8.01 for both CW and NW. You can use GB points to further reduce price! 
Of course with all the funky shipping rules I have no idea what shipping cost per country is.

I have the F2S, and although it has strobe in main mode sequence, I think this light is absolutely awesome for this price.
