Even if a 360 hasn't already been banned, there's no guarantee that it hasn't been flagged and will get hit by the next ban-wave, so it seems rather dodgy buying any second-hand 360 if you want to use it on Live or use the HD install feature.
I'm generally too nervous to buy second-hand mobiles as well, as some twisted seller could easily report it stolen and leave you with an expensive paper-weight once you've bought it.
