For removing bad SMD chips? Like as in QFP, SSOP, SOIC, DFN, and the like? I would use hot air station. Nozzle smaller than the body of the IC and blast the IC, not the pins/board. Bad for the IC, of course, but I'm removing it because it's bad, anyway.
If I was working on expensive boards, and I was making good money doing it... then yeah, I might get spendy on tips, too. But the cheap tweezer accessories you might get for a 936, I've had a set or two somewhat like that, and it's not worth it. 936 doesn't even have enough power to remove anything but an 8 pin chip, tops. It might be useful if.. never mind, it would probably never be useful, IMO.
