The rumor on the Circuit Specialists station I posted is that it's made on the same assembly line as Hakko units. A buddy has been using one for quite a while; they don't seem to be a fly-by-night company.
I did get a smaller tip than the standard one (since I do a tiny bit of SMT work).
I had a Weller that looks similar to the WP-25 (not sure what I had, as it was so old all the lettering was worn off, and I couldn't find the model number to replace it with an identical unit). It was a good one, and lasted for years.
