buying stuff EBAY is not such a good idea in my opinion...what if you buy it and you go to hook it up and its blown right out of the box? then you have to send it back to them and wait longer. id rather pay an extra 25$ and get it from a retail store that i can return it to. best buy doesnt offer any type of Service plan either.(do they?)
at least from a mom and pop shop or BB or CC they offer protection to the unit.
