Received the new units today - in brand new TRW boxes, with 3 year or 100,000km warranty stickers on them - if it means anything.
Opening the box, inside are what look like brand new Lucas items - All the fittings look brand new, freshly machined etc. I guess they could be refurbed, but they are advertised as new and certainly look it.
Won't get to fit them this weekend as the brake hoses haven't arrived in time

I say go for it, bargain price! Although the seller doesn't have many left..
