Just a word of warning, IF he should get back to you, then beware, it turns out that he's a rip off merchant.
He came to my house for me to try to sort his problems out, which I did. I gave him most of the spares he needed to sort the machine out and sold him a new mech.
When he got home he realised he'd picked the wrong one up, so I sent him the right one, and he said he'd send the other one back to me, with the postage for the second one inside the parcel.
This was weeks ago and nothing has arrived, when I gave him a nudge about it, he said sorry and that he would post it out asap.......... still nothing and now doesn't reply to messages.
Just thought you ought to know!
