Default ZTE U950 Worth?and where to buy?

Hello guys, I was searching a Chinese website and found this phone, it has a beast CPU and all that, does it worth? Will it last long enough or will I have hardware problems all the time?

Also where to buy it?I found it from 90$ up to 200$+. On Aliexpress I think I found the cheaper price but it does not support PayPal so I am worried. What's the catch, if any on the huge price difference on each website. Do you know any cheap and reliable? I live in Greece btw.
