I thought mine was cheaper but I guess not I have this one
ebay.com link: S 993A Electric Vacuum Desoldering Pump 100W Solder Sucker Gun 350 450 110V
the station you have there looks similar to the gun ..
Pros for mine
easy to clean and remove any jams
easy to replace filters
works good for thru hole and surface mount components
Cons
when you have a big chip or a daughter board for a system 80B when the holes are small and the board is soldered on both sides it can not pull all the solder out of the holes
you have to use chip quick solder and then clean up with the gun
