Any other C8 XM-L2 U3's?

I’m probably going to keep this one stock for a little while (until I get bored with it I’m sure). If it doesn’t make a difference then I guess there isn’t much use in purchasing that one for the extra $. I’d like to find one that is shipped from the US as I need it within the next 2 weeks or so.

The XinTD C8 look awesome (especially the green o-ring on the head) but it’s twice as much as the Convoy C8 you listed.
