If you import a PAL model, try to do it from Germany, Austria or perhaps the Netherlands as those countries tend to have the cheapest international shipping rates. For the same reason, avoid countries like the UK, Spain, Italy, Sweden, Norway and so on where shipping tends to be expensive.

Very much true.

As Marko wrote and I still vaguely recall, the CIAs used it. Even if TOD clocks AFAIR has never been accurate enough for any serious work with them.

It all depends on the intended use. If this is to get full compatibility, I would say: grab along with the 64 an European DC/AC converter and after supplying it with the 12/13.8V you should get 50Hz plus be able to use the original EU PSU as well. The more expensive ones should give even something close to sine waveform on the output. Again - to me it all depends on what is it to be used for, but options are there.

If the C64 was in any way an uncommon computer, some collectors might have objections about making changes to units so they no longer match factory condition, but since every man and his dog has a pile of them, nobody should need to worry about that aspect neither.
