Parts may be ok,I have no experience on those, but you will be held hostage for ransom = good feed back on EBay.... until you give them good feed back you wont get any....
which its not how its supposed to be.....If i`m selling something and someone pays me , I give them feedback based on them paying me, not based on how happy they are with my part! and leaving myself the chance to 'retaliate'

We`ve had some 'discussion' on this site w/ Ms Tamraz about that policy...she joined this site for a short while b/c of this..
