New lens for skyray king?

As above, i managed to shatter the lens in my week old king (insert frowny face here). Where can i get a new one? Kaidomain has some which are 54mm x 2mm in hardened or multilayer but i read that the original lens is 54.87 x 3.03mm. Would the kaidomain ones be close enough and which should i get?
Thanks in advance.

Anyone? Please!
Surely im not the only person who has cracked a lens on one of these bad boys!

well...I could reccommend for a replacement,but coming from the US it may not be cost effective.Chris can make a lens custom size,just email him to see how much it will cost.I got an a.r. coated lens from there for my king for like 7 dollars.
