 Good points... I am only bothered a little by most of the stuff. If you need the stuff fore safety, I can understand that, even better if you hide the best  you can though.
On the Museum birds, the reasons you list are just why I find it inexscuable. LOL, I figured it would be easier to restore a static plane cause you could use the warn out stuff. 
Toad, 
 I have some clue as to the costs, they are so high in general whats a few hundred grand here and there?
   I would rather see an incorect one in the air then nothing at all. 
MT I can tolerate and still enjoy the inacuracies of warbirds, hell I can only catch the major things.  Replica cars do nothing for me at all, especialy the fake fiberglass cobras. Now I know the real ones are up past 250grand at this point, but a fake cobra is a fake cobra, just as bad as the fake Lamberginis based on Fieros.
