It looks like a lot of people can get by with the Radioshack soldering iron, which makes me sad because my 40W Stahl soldering station should be just as good, if not better! As a grad student, I wanted to build my crack on a low budget. It's frustrating... Could it be that I'm soldering incorrectly? Is there some cleaning issue that makes the solder "ball up"?
On the plus side, customer service at Bottlehead couldn't be better. Already got a 120V PT on the way, should be arriving soon. Thanks Doc and Queen Eileen!
