To be fair this thread is from 2010 and we haven't heard much about any issues lately so I assume they're one offs.I wanted a replacement nearly £50 a pop from trade tiler a CK850 125mm. I think if I remember right I sent it back through David at trade tiler then Gary the Marcrist rep phoned me. I use ATS now anyway.
ATS get rated on the forum too. So either way not bad.
