I've just unearthed this, so might as well move it on 
One M739 XT mech in long cage, 8 speed flavour. Mechanically really strong and was working great until I removed it a month ago from the bike. No loose pivots anything like that either, and jockeys are still in good shape. I've had is apart and given it a check over and regrease as well where needed.
Cosmetically not too bad either. A couple of scrapes near the pivot bolt mainly and the odd scuff here and there. The rear cage plate was looking a bit tatty (they are steel on the long cage) so I brushed on some primer and blowed on matt black paint. It isn't the prettiest job close up but looks fine at a distance and will keep the rust at bay.
I'll say £15 posted for this one. Pictures are below...
