Exactly. If you're just doing a little repair work here and there, tossing in a region switch, building a couple JAMMA converter boards, etc. then a moderate quality iron is fine. If I still had my shop and bench area like at my previous residence and was still doing 4-6 mods a week as well as other repairs, I would invest in a nice soldering station. I was leaning toward that before moving. If at a later time I go full bore into the arcade scene then I'll probably make the jump for a nicer setup since repair is the order of the day on that side of the hobby.
