OP, you should just save yourself the trouble and go ahead and get the Dinotte XML3.
It's US made, with a 2 year warranty.
The 1200+ is very nice too, 90 bucks more, but with more output it is a little more future-proof.
This guy makes a fine headlight, but there may be a long wait due to supply/demand:
