Don't buy a model which is already obsolete 3-4 years ago as there will not be any spare parts available like what we experience with Creative's s750, from Creative Labs Megaworks 550 or Logitech z680. Both these series already have newer series replacing it and definitely you will be asking for trouble if there is problem when the warranty is over.

My advice is to get the newer series with caution; go to their forum to see what other user says about the speakers and overheating sub+amp is one of them. Price may be attractive but eventually you will end up with a lemon and you cursing and swearing. These are like all computer hardware if its an old series you will know that it will not be entertain by the retailer and distributor when there are problems. YOU ARE ON YOUR OWN, BRO. Don't buy it because of price , there are always a reason why it so cheap currently,believe me.
