I agree with most of that. I've worked with basses with laminate bodies but good necks, and adequate electronics - and they sound good. But time and care in putting things together with ADEQUATE parts will yield a good result. When you have "crap" parts in critical places - say, neck and electronics - you will get a less satisfactory result. But IMO a cheap body, tuners and bridge aren't going to hurt you. (Tuners? All they do is hold the string. If they can be adjusted and don't slip, nothing else is needed.) And I'm NOT convinced that body wood makes enough sound difference that most of us can hear it....and not nearly as much difference as strings and electronics.
