The RC-C6 is available in several places - this could be the cheaper Q3 version, it is not possible to tell from the pictures. I have one and as zooming lights go it is not bad at all. I'd say it is worth it. Lightake had the Q3 version on offer a while back.
The Skyray S-R5 is available is several variants. Good light, well made, nice body.
The Trustfire F23 is one of my favourite lights - lovely but heavy. The switch can be fragile. Fran82 killed his one with a drop.
That is the new body shape 504B - someone here has one - but my memory is failing on who it is.
The SST-50 light is essentially the same body as the Uniquefire L2/Solarforce L2/old WF-504B. They are all P60 lights and I'd not buy any P60 sized SST-50 light as it is not well enough heatsinked to be driven at the 5A an SST-50 needs. Nor is 5A out of an 18650 a clever thing to do unless you buy (expensive) IMR cells. It is probably little or no brighter than a well-driven MC-E and costs a lot more.
Yes, I know it would never perform 100% on a p60 dropin with just one 18650, I just think that, what the heck, an SST-50 is an SST-50, how bad can it be? And I also like the body so it is not so big difference to add $15 more and get the dropin too.
EMS is a lot more expensive than HK Bulk Post which must be around the world's cheapest. I found this price page but I don't know what the currency unit is.
It would seem to cost either 295 or 355 currency units to send 1kg to Greece. I presume the price is in Renimbi/Yuan but may be in internal non-convertible Chinese currency. 335 Yuan works out as US$53
I always choose EMS (even on DX) instead of HKP even if it's more expensive. It is fast and I always get the package (for example, my last order on DX was split in two by their choice, EMS package arrived 5 days after they sent it, HKP package hasn't arrived yet, two months after send date...).
The "way" to minimize EMS cost is to make less - bigger - orders, in DX sometimes it costs even $0 to choose EMS on bigger orders ($150 - $200).
Anyhow, SW doesn't even have HKP option and their quotation (I guess the cheapest alternative) was with EMS.
