I have an x4s with 9 different ND filters (PolarPro and other brands) for sale and I live in the USA that I will sell for $525 (US currency, PayPal only) if you agree to pay for shipping. Currently I am not at home so I can’t post any pictures but give me a couple days and I’ll post them. It has been well taken care of and in perfect condition. And it is still in the original case.
I just wanted to say that you do know the x4s is no longer available in most places other than from a 3rd party, don’t you?
And originally the price tag was $599 so with all the ND filters I have for it this is quite a good deal but I am willing to part with it if you’re interested.
I just saw one on eBay listed for $760 without the ND filters!!
