Funny, I never followed your first link!
I'd have bought the same unit if at the time I was looking it wasn't 125 dollars more than the price you listed.
Be wary of quality, this is obviously a Chinese product. Amazon's return policies are often generous, but test the hell out of the unit when you get it. My Iron station alone cost that much but that was 5 years ago, the hot air gun can be REALLY useful for bulk desoldering and many other tasks as it's temperature controlled (heat shrink tubing, board pre-heating for hand soldering, plastic forming etc.. etc..)
