I got mine as well. Also near mint, except for the missing tripod collar. A nice and small lens, ideal for carrying on long hikes, I think. The build quality is as expected very high. No comparison really to any of the modern zooms in particular.
The weather hasn't been all that nice over the weekend, so I only had a chance to get a couple of test shots to see if everything is OK. First impressions are pretty positive, even wide open. The colour fringing Bjørn mentions in his review is quite obvious though and will need to be dealt with in critical shots. But other than that I find the image quality if anything better than that of the 70-300 VR which does get pretty soft at the long end.
I'll experiment with my TC-14b once the weather gets any better, despite Bjørn's warning that the image quality of the combination isn't good enough. Even if it doesn't work that well, I wonder if the quality is good enough for record shots of birds.
