300 dpi is my standard too. However, occasionally 300 dpi scans are vulnerable to Moiré patterns, and sometimes quite noticeable ones, big waves going across the scanned image. I have never managed to get rid of those posthumously with the Moiré-pattern-removal features offered by picture editors. There are only certain mags that are particular vulnerable to that.

Not sure whether I did do that in this case, but anyway the result looked like this:


This usually does the trick. I think there has been one or two occasions when I had to resort to really desperate measures and move to 1000dpi, but that is exceptionally rare.
