Anyone knows where to buy this new version?
I already contacted a few sellers, but it seems they only sell the first version of this charger.
maybe the old stock must be sold first?
hehe, thanks for the link how2 
Do you have any experience with this company?
Gonna ask for sure if they sell the II version as mentioned on there site.
QCG has been around for a while - they are older than DX. They are also known as SZWS - who sent me the Xtar lights for review. Serena from SZWS is often around here.
My first order from them was in around 2005-6. Before I even knew I was a flashaholic though I spent quite a bit on light-emitting devices. Before I even knew CPF existed.
They have never got any order wrong or failed to send me stuff. Since they ship from Shenzen, they tend to get stuff to you slower than DX (As in 3 months back then), but they don't mess you around.
They did (I've no recent experience) answer their emails quickly and would sort stuff out for you. They weren't the absolute cheapest usually though for the stuff I was buying they were around 1/3 of the price of the previous (HK) supplier. They had a far wider range of light-emitting stuff than just about anyone else back then - and from a quick look around they still do. Their service was better than the HK guys but you paid a bit more for that. IMO that is worth more than what they charge for it. My first non 5mm LED LED light came from them and was a good deal. The folks that became DX and KD would have sold it for a bit less, but both of them had their problems back then. KD has got a lot better, DX hasn't.
Personally, I'd recommend QCG. And I've have recommended them just the same before they sent me free stuff for review.
Just don't hold your breath waiting. Fast, China Post wasn't - I've no idea if they are faster or slower than HK Post nowadays.
SZWS = XTAR.
It will probably be shipped with Singapore Post which is quite fast (I wonder how that works, Shenzhen is quite far from Singapore...)
They ask 10.58 $ for shipping with China post Airmail.
Not cheap and I hope for this price I don't have to wait a few weeks to arrive.
They also refer to the Retail Site who is totally free shipping.
But there they don't sell the WP6II, only the first model, the WP6
With that 10.58$, it is still it's cheaper when bying here in Europe
