So... Looks like I'll be picking it up! Thanks for your insights.
All those things are interesting, but this lens is great without them. Also, the new Series II lenses are coming out at prices 40% higher than the lenses they replace. I'd love to have a Series II 500mm to replace my current 500mm, but it cost $4000 more than I paid 18 months ago, plus I couldn't find one to buy, even if I had the money and inclination.
Take this deal. You'll always be able to get your money back out of a top performing lens.
