Ooh. Hard for me to get over my gut distrust of this thing in concept. I've already conceded to carrying around two toolbags (I flatter myself, they're just canvas carrier bags really, I have tool bags but I'm a lazy f**k) around for pinball repairs not-at-home. It's not just an iron you need after all, it's all the cleaning supplies, numerous spare parts, tools for bashing/loosening everything plus everything else... the soldering station is a drop in the bucket in that regard.
Now when the day comes that people start asking me to repair their SMD pinball machines, and I have to start bringing a hot-air rework station on top of all that as well, is when I'll probably start trying to reduce the weight of those bags a bit.
Okay, in all seriousness and Luddite-rant over, I am a bit hesitant about the fact that it looks like it has proprietary tips. That's a legitimate concern for me. Long gone are the days that I ruin tips immediately with atrociously poor technique and physical abuse, but they inevitably wear down even if you're pristine in form - and we know that circumstance and form will not be pristine as we're looking at this with a view to field repairs bent over a pinball machine.
EDIT: looks like they're specific tips, and they're not super cheap. Bit of a downer. The thing also isn't quite cheap enough for me to justify as an impulse buy, even when I think about not having to lug the solder station around...
...I do fancy one though.
