I would like to make a pixel-art mosaic and found out the existence of part 65803 for building the base board: https://www.bricklink.com/v2/catalog/catalogitem.page?P=65803#T=C
Alternately, there is a chinese clone available under the brand YNYNOO: https://www.aliexpress.com/item/1005004221907158.html
My consideration to get a third-party part is because buying the genuine LEGO versions in bulk seems difficult. There are lots of suppliers on BrickLink, each one with a small inventory.
Is there any knowledge about the relative quality of the third-party equivalent? I guess it may be a tad lower than the genuine part, but the supplier is able to sell enough for my needs in one go.
I am looking for a solution with the least mental surcharge ( = reducing having to deal with a lot of suppliers) to buy the parts, and ideally not too expensive in shipping fees.
