Best of all was the nib. It's smooth but with just enough tooth so that I feel a sense of control. It's fine, but puts down a very wet nice line with no dryness or blobbing, even though I hadn't flushed the pen before fill it up with (ugh) blue Quink - the only ink I had handy. It seemed to me incomparably better than a Pilot disposeable fountain pen (which costs about the same) or even a Lamy Safari.
For those who care, I tested it a Moleskine (cheap skate note: I wouldn't normally pay Moleskine prices for their sort of quality, but I got a deal..) The 329 has a reputation for being a good pen for a Moleskine, and it worked perfectly for me.
Second best was the price - an insane $17 "Buy it now" price on ebay for THREE pens including airmail. The seller was mars_0001 and he posted instantly - I bought the pens on a Friday and had them Tuesday morning. Mars seems to have a small stock of constantly changing pens on ebay at prices much lower than Yan Cheng and the other major sellers. His stock seems to go very fast, so it's worth checking frequently. Communication was excellent.
I've read that there are two sorts of 329 available: older and better, and newer and less good. I don't know which my pens are.
The downsides... Firstly these are not good pens for people with bigger than normal hands. In fact, they're too small for mine. An inch extra length would help as much as more width. But my hands are on the large size - I'm XL or XXL man's glove size. A more average male friend found his a perfect fit. Secondly, the pens are extremely light and don't balance well with their steel tops on - the tops are long, nicely engineered out of steel, and may well weigh more than the rest of the pen.
Overall - a terrific buy unless you have bigger than usual hands. I really can't believe how good the nib was. I'd have been happy with it on a pen costing ten or twenty times more - this may just be my lack of experience with FPs - but on a pen costing the same as sandwich, it's still an excellent deal.
