Trying to decide between a new Onkyo 5400 7.1 or getting a used Onkyo 6300 7.1 system from Accessories4Less with their Warrantech warranty. What do you guys think? Max is $400.. I want a budget 7.1. I know plenty of you would say invest in fewer speakers, but this is just a budget set up that I just want get me by for the next 2 years or so.. (Not sure if this is the correct place to post this)
