I have a US QL, therefore I have a US QL PSU ;) Though I am capable of building a replacement PSU if needed, or converting a UK to US PSU. Also, US houses have 110v and 220v circuits, so 220v is available if I get really stuck (and don't mind QLing on the tumble dryer). The 50/60Hz issue is a non-issue. I would just replace the smoothing capacitor with a slightly larger one.
As for the display modes...I would definitely prefer to use a UK/EU spec QL. I'm only aware of two US QL users and they're both ex-pats anyway, I think ;) Dave PS: and I am looking for the PSU, and not finding it. Fate, it mocks me.
