john whittakers version - it comes with the roller, whereas the pessoa you have to have your own roller. very good quality but obviously not the cheapest
I have Mark Todd's version - didn't personally get the JW version because when I tried to get it a whole lot had been recalled because they keep breaking...... I got it online at Ingatestone and they sent it within a few days.
I made mine, works fine although it would have been nice to have one that came with instructions, I've been trawling websites for info on high tight to set it etc
