This is a really good pen at a great price. Great styling too, as long as you like the black & gold option:

I haven't owned one but I did try one in the Pen Shop a few years ago and very nearly bought it for about £150. FP forum review here:

IIRC it was a very smooth nib with a little bit of flex (neither stiff nor true flex). Would be a good daily writer.
There are some other cheaper Watermans listed which are OK for the sale prices, but those cheaper ones have basic steel nibs and I find them quite scratchy (not as good as Parker or TWSBI at the same price). One of my first fountain pens was a Waterman Hemisphere, which I soon replaced with a Parker Sonnet and never looked back. The Waterman is better looking, but the Parker is a much better writer.
