$1200 isn't unreasonable. Not all Chinese shops are the same. An Eastman SB59 made in China is $2000. It's not the same guitar as an AliExpress Chibson Les Paul for $250.
If they are using a genuine Floyd Rose 1000, that's a couple of hundred bills right there. It looks like they are using a traditional headstock, not a scarf joint. I do like the way they are doing the neck joint on the Ascent+.
