I would try a few of the guitars he has buildt before I'd buy. There are lots of "luthiers" out there building guitars that just dont play or sound good.
The price however, is not unreasonable considering you live in Denmark.
Well, I'm not sure I really need help, I just asked to be sure. Because I have video clips and everything with a guy playing one of the guitars, and it sounds great, and I don't think I would be able to get any other guitar in that good quality for the same kind of money, and I don't want some factory made japanese guitar or whatever.
Unfortunately, the guitar luthier you're looking at is unknown. You'd be spending $1100 on a guitar that might not measure up to your expectations. The guitars that I saw on the website look more like your standard, budget metal axes than something really special. This may work for you just fine, but I'm not seeing anything that shows off the luthiers craftsmanship there (besides the odd designs). The quilt one made for Martin Christian offers a pretty poor top and if that was designed for someone the luthier obviously loves (due to the various plugs throughout the website), then I'm not sure what he would design for the average customer.
