I bought new and used one. Both are working well. Just difference if it has some scratch or not.

Sturdy mechanism, good quality finishes, and the design with handle rounded off on both edges which are comfortable to the touch, precise operation...nowadays we rarely get to experience a product with these positive aspects in my opinion; good job manufacturer, this definitely wins me over the design names products out there which falls short with design, functionality and reasonable price point. Hope this help, please do your own research. Highly recommend! Only thing, hope this thing will last, as we will use it and not abuse it; time will tell.
