Hi there... I would guess that this is a forum where people go through the experience of getting rid of their Bose home theater systems... anyway, I have a 17 year old friend who wants to sell his Bose Lifestyle 18 system to help finance a real home theater purchase... what, generally, does a used version of this system sell for? And could you guys suggest any ways to make selling such a used system (he doesnt have the original box it came in) more easy? My friend is in Canada. Thanks!!
