I find batteries a pain, especially as there output isn't constant over
their lifetime, therefore I'd love to be able to power my motors from the
mains. I'd like to know what methods their are are doing this. I'd prefer a
purist option but I do know which end is the dangrous one on a soldering
iron. It also has to work in the UK, home of the three pin plug.

Purist approach is to use a 9V train speed reg and LEGO(r) wires from the
speed reg to your motor(s), possibly through the polarity reverser switch to
give control. The speed reg is powered from a wall wart trafo so if you buy
a UK train set or UK used speed reg (should not be too hard to come by) or
even pay LD's high price for a new one, you should be all set. The UK wall
wart will have the appropriate 3 pins for your funky mains points and will
be 220v compatible.

The wall wart from a speed reg can also power an RCX that has the power
connector (1.0 but not 1.5. I do not know if they put it back for 2.0 or
not) if you want to go that way...

4548s were 5ukp in Toysrus a while back

Someone in the UK has a UK 3 pin adaptor for $5

I'm sure you can find a UK person to trade a controller.
