I was able to find an old mountain board, unknown brand for NZ$70.
New Zealand, the import duty, and shipping always makes it expensive.
Lately there has been some Flipsky products listed by a shop called Drone-express, that is still expensive but at least you know what you are going to pay.
Flipsky is listing AT trucks with 8in wheels. To me they look very similar to the DIYeboard/L-faster ones. The concern on this forum of those is quality. Any real-world users?
