(desoldering)-looks like 廣東省, China -- got out the copy machines of the Fr-300 Desoldering tool!!

awesome, i keep mine between 375 and 400c, that way its got enough stored up thermal energy to suck out 4 layer & GRD planes. but my new 1mm tip already turned purple.. kinda freaky. it still works like a champ… as long as i keep the tip clean and tinned.

I am thinking about getting a pencil/small type heatgun, and strapping it to the side of my hakko.
This way, any time I run into issues with multilayer boards, I can preheat.
I do that now, but it takes both of my hands = not elegant.
I never get the tip hot enough to power through multilayer boards by itself. For one thats a bad idea as its hard on parts, and two thats an extremely localized spot for a heat source and can break hairline traces in the inner layers of the board due to thermal shock, if they connect to that point.
been there, done that.

Pushing the envelope of PCB rework tolerances? ;D
I'm thinking if you ebay x-tronic... you will get one that is pretty good quality...
i'm pretty sure that you want the one that pushes the air to the wand, from inside the unit.
the ones for 59 dollars that have the blower inside the wand might have some quality issues.
iv bought 2 of that kind, the super cheap kind with the blower in the wand. and haven't see first hand any issue with em.
BMOW has one... my wife has the other.
Sounds like Others had quality issues with the cheap cheap ones.

I'v got a atten 858d (it is exactly the same as the first one uniserver posted, expect for it is branded differently) it cost me about £40 a few years ago and it's been really good, I have even replaced big BGA chips with it 
(Xbox 360 GPU's and CPU's, with the help of a board preheater (which looks rather like a griddle.... ))
I have heard of some quality issues with them, but i haven't seen any problems yet (my only gripe is that the cable from the unit to the wand is not heat proof, I can't count the number of times i have melted chunks out of the cable (I haven't got through to any of the conductors though))
