Started out using SRT's. Used to them from the earlier models as 1000 (still one of my favorites maybe because of the pain of having to tweak the mechanisms so often - maybe not that often - but I like making improvement). Advanced with them through semi-automatic systems and software upgrades. Good stuff. However, I really like the newest Air-Vac stuff for BGA and other as solder fountains with air compression to clean holes before device reinsertion (saved my skinny butt many times). This stuff is clean, straightforward, compact, and easy to learn and use. That's the most important part of the equation. Operators cannot be overwhelmed by inconsistencies, as you well know. They get frustrated and become creative, no matter what rules may be imposed. Sometimes they come up with good answers, but that's not their primary responsibiltiy. Rework is.
