We used the cheapo Stahl SSVT under a different guise for a S.E.X. kit building class ten year ago, one for each student. They were pretty bad, as I recall I had to pull out one of my bigass Wellers to help the guys solder some of the bigger stuff like binding posts.
Not that this is much help but I had the impression that a lot of the problem was that the tip just didn't transfer heat very well. I don't know if there are any aftermarket tips for that iron that might be better.
Oh yeah, I seem to recall that the black plastic ring around the iron holder is held against a spring and will probably fly off at some point. Seems like we had 'em popping off a lot of the stations over towards the end of the class.
