Ebay is by far the cheapest place for these... you can get away with just a 1A but its tight.... 2A is more than enough for an old woodrail.
Jaycar do a 5A and i have 4 sometimes 5 machines plugged into this.. its never tripped ( has overload protection), but at $230 its an expensive option.

Im curious though... why would a French machine have 110V??? Whole of Europe is standard 240V
