Funny, this would be my reaction if we were talking about vehicles and someone was spending money on an import!
Just as they tell me imported cars and trucks are manufactured better now than my experience witnessing them rust apart in NH while I was in High School (mid 1970's) Century Arms became an
ISO 9001:2015 certified manufacturer back in mid 2018.
I took some time to go read what that standard is to a manufacturer. (GOOGLE has lots of info about it)
I ran across the contractor that Century hired to train them and coach them thru the certification process.
"Century International Arms was seeking to pursue ISO 9001:2015 certification to improve business systems and results. They wished to be ready for their registration audit in early 2018 and preferred to be trained and coached to develop and implement a quality management system that worked for their team."
To my knowledge they are the only AK manufacturer to hold that certification.
It means the VSKA they build now is coming from a manufacturing operation that follows the same standards as other US firearms companies, like these guys:
Barrett receives iso-90012015 certification
ISO compliance also means you can compete for DoD and other US Gov't contracts.
CUGIR & ZASTAVA can't be ISO compliant because they still hand fit parts (I watched those on-line video's).
Parts interchangeability and a uniformity of the manufacturing process, established QC standards, ISO dictated management processes and internal documentation are all part of ISO and mean you produce consistent product.
That means any VSKA you hand to RobSki will perform like the one before it, given the same test routine, ammo etc.
I would feel pretty safe spending that $480 on a used VSKA.
