Hey I have the same question. I am also between a gweike 6090 and a thunderlaser Nova 35 or I am even looking into the bigger models the 1000x900 Versions.
I got a offer from gweike for the 1390 from gweike for 3800$ to that I have to add 19 importtax and other taxes plus extra costs I am not sure of yet.
When I buy a thunderlaser here in Germany the costs are 13700 € incl. taxes and I can just pick up the machine.
The difference is this. Thunderlaser has a German and a American distributor. They offer a good customer support and they help you when the machine has problems. They have also done the necesarry Safety Checks so the fullfill all standards needed in the EU.
I talked directly tp gweike and they dont even have a user manual.
Also there CE Marking is not correctly done. They sent you a CE Certification but they dont have a signed Declartion of Conformity. So they dont meet the standards to import into the EU.
And I run into the risk that the machine will be stopped by customs.
