Harris-Wilson
The Harris-Wilson corporation creates components that are the equivalent of a sports car: they are not very subtle, but high quality. Together with Elander, Harris-Wilson charges a lot for their components, but it is difficult to find better performance than Harris-Wilson components. Elander and Harris-Wilson differ in the emissions of their components: Elander creates quiet components, and Harris-Wilson creates loud ones with better efficiency. If you aren't prepared to raid your savings to get Harris-Wilson components, Xiao Sa provides reasonable performance and efficiency for less.
