Ronan – Good luck in your search. I have the Alba 1A which is more or less identical to the Elliot 10M. I use mine a lot – great fun!
Just a tip – The correct speed for the motor should be somewhere around 900-950 RPM. If however, the speed is higher (say 1500 rpm) it will still be OK but the shaper will work a little faster. My single phase four pole motor runs at 1500 from memory but is still very usable except that its to fast to use the shaper with top speed knob engaged.
So in a perfect world you want to see a single phase six pole motor running at 900-950 or a three phase motor controlled by an inverter.
Be prepared for a lump – even the 10" machines weigh approx 1/3 of a ton.
