I'm a new to the 3D printing world, am in the process of choosing & buying the patrs for a 3D printer I'm building, and I've been debating on whether I should go with an *official* more expensive Arduino Mega 2560 V3 or a cheaper SainSmart Arduino compatible Mega 2560. Is SainSmart a reliable and quality brand/product? Has anyone had any serious problems with the company or their products?
