Well, it arrived today, and it's even better looking than in Tom's picture. Loaded it right away with Noodler's Black and tried it out. It's not too skinny after all! In fact, it feels much more comfortable to hold and write with than would a ballpoint or rollerball of the same diameter. It may be slightly better balanced posted, but I'd rather not risk scratching the gold.
The 180, if you haven't seen one, is unusual in that it is designed to write lines of two different sizes. You turn the nib over to change line widths. It is true that many older pens have nibs that will do this "trick" but the 180 has a very different nib design -- it's dead flat and triangular, and has a feed that is designed to assure ink delivery with either side up. In the case of my pen, the nib writes a very nice classic medium line and an excellent extra-fine the other way. I say "classic" medium because the line is not as wide as the one laid down by my medium Sonnets and modern Duofold.
I had heard here and elsewhere that the 180 is temperamental and not smooth. This has not been my observation with this particular pen. Ink flow is smooth and the pen starts easily. No drag or scratching from the nib on either side, although the extra-fine side seems to be just the slightest bit dryer than the medium side (as might be expected).
This is a great little pen, and it might just become a favorite for letters, checks, and memos.
