I saw the new Jinhao 599 on eBay several weeks ago for less than $4.00 (!) and decided to pick one up. It certainly looks like an "homage" to a popular German pen whose name begins with an "L".
It is surprisingly well built and features a really smooth medium Jinhao nib. The clip is firm yet springy and it is well-balanced with the familiar triangular grip section popularized by "you know who".
The pen is so nice that it makes you drop your jaw drop as what kind of quality can be achieved at such a low price. It makes me wonder why the "real thing" sells for almost 10X the price!
Check on my brief YouTube video on the 599 here.
