@Xiefei: "They take that pretty serious around here".
Indeed. Do as the Chinese do and hop across the border into Myanmar and chop all the trees you like.

Is it legal to cut down trees in the hills?

What do you think ????

If it has a separate power supply it is easier to buy a new one for the local voltage.

The other way around might be more useful.

Most equipment nowadays is multi voltage. Read the instructions it might say something like 100-240V-AC 50/60Hz. In that case you can use it straightaway.
