New, the 3806 should be excellent. As far as the cables go, it isn't clear what the basis for the comment about a difference in component cable quality is, since it's difficult to in fact find any. Reasonably priced HDMI cables are available, for example here. One point is that for very long runs(e.g. over 15')24ga is often suggested rather than one of the thinner cables, but this might not apply to your use.
