have got a decent cemont set so i'm sorted 4m lead on the wire feed and 3m from that to the main unit. the joys of having 3 phase!!
know what you mean about home sets, tried a nasty thing from halfords (?) that mate was having problems with, i swear if the lead wasn't dead straight it would struggle to push the wire through!!
must have been a sip, i have one at the min and its the only brand that was giving me the same problem, may get a decent welder some time soon too
