2 ignition barrels broken....

hey all, about a few months ago my bike broke down because of its igniton barrel, the wires in the back were faulty and everytime they moved it would cut out the bike completly.
i had this problem fixed by a mechanic which he says he got it from the wrecker, and when he got the barrel cut for my keys, i didn't realise this until a few weeks ago that when the ignition is on the "ON" part you can take out the key... i went back to him and he said thats normal?
anyway, that barrel that he replaced cut out again on last sunday, same deal, the wires in the back, if they moved lef tto right, just lightly without any hard force it would cut out. He ( the mechanic) said that it was my fault because i kept movin it around, which is all lies because he chnaged it and i didnt touch it. Having the bike turn of completely on me at 80 km/h isn't something im looking forward to..
i'm currently using another ignition barrel of my other zx-2r which is running fine, works a real treat. they key dosen't come out in the "on" position, it doesn't cut out or nothing...
has anyone ever heard of this problem? i went to the wrecker but he's charging me $80 for a barrel and it didnt look like it was in good condish..
should i get a brand new one?? and how much are they..
also.. how often do these wires stuff up.. i've had 2 barrel break down in 2 months... within 5 rides...
cheers.
