Mine is probably at the higher end of low end but I am completely happy with the system and wouldn't change anything except maybe bought a PS3 vs my current BD player. (Hind sight is 20-20). Given a bigger veiwing area I would probably do some changes. Of course this is all based on my personal preference.
