These people make them for other comapnies and sell their own. They are not top quality but I don't think your looking for 1000 units a day for 20 years.
http://www.aoyue.com/en/products.aspJust checked your links and the eBay one is an Aoyue. I have several of the things they make and have no problem with them.
I have a 968 rework / soldering station and the iron is really good. I normally use a Weller iron, temp controlled but I do prefer the Aoyue to that. The rework part is good and comes with several tips for different shaped chips, there is a full range available.
I also have a 950 tweezer set which is OK but I find the tips a bit to big for modern SM. It's fine for stuff that is a few years old when SM components were a bit bigger.
I just sold an Aoyue pick up tool on eBay, couldn't live with thnoise and din't need it, tweezers work fine still, I don't do enough to need a vacumn tool.
For desoldering I use a Pace, I don't think you can beat them with anything.
