Darren the Corsair is looking great; it should be awesome once you've finished it up.
Frank your hobby cave is enormous, just think of the stash that will fit in there
Bob aside from what has already been stated on pre-painted PE, the only other thing I do is apply a weak wash of raw umber to the harnesses to blend them into the rest of the front office. I find that they tend to look just to "new" otherwise.
Cheers
