I think you could go on the huge selling website beginning with E and get a basic but full size one.
I bid for an older model Frister & Rossman - 99 pence and I got it! Very surprised no one else bid against me.
(I had to pay courier costs too).
It had a broken foot pedal - but it was glued together by my FIL and worked well for 10 years.
Baby Reindeer - anyone watched it?
