Mine came from Creative Engineering, nice helpful folk and delivery very quick.
The only minor criticism could be that the toothed piece welded to the beam didn't match the curvature of the tube exactly, but was close enough not to be a problem. I spoke to Dave at Creative to question the method of welding,bearing in mind the toothed piece is a casting and the tube mild steel. The friendy reply was that the casting has a high 'something' content (probably carbon, can't remember) and welding with a conventional mig set up for mild steel would be fine.
We only welded the sides, not wanting to risk distortion and everthing has been fine. Hope thats of some help.
