I have bought JBC DPM-B in Kardilab in Slovenia for 48€ with “Posta Slovenia” with tracking number for 10€ shipping costs to Brazil.
https://kardilab.com/shop/consumables/jbc/jbc-dpm-manual-solder-paste-dispenser/I bought it because even though the material is perhaps 3D printed, it must be of better quality.
As always it depends on each one.
Most of those for sale have freight to Brazil from international private carriers, some charged more than 150€ for shipping.
Concerning Kardilab, they state they have also a really good responses regarding fluxes and soldering pastes. They also have a repair shop and they use all of their products. This was the reason their online store started, so that they want share all the good tools with others.
I will try their soldering fluxes and soldering pastes next time.
I hope this information is also useful for someone else.
