I went Best Buy to get my store credit from my last receiver under extended warranty that died which was an entry level but really good Pioneer that I really enjoyed.So after dealing with customer service they tell me to go and pick out another receiver and off I go to the back. I had my eye on the Pioneer 815 after hearing and reading so many good things about it then a salesman tells me how good of a choice im making but as im walking to the register with it another salesman says I should get the Yamaha 5840 instead.I also asked about the cheaper Pioneer 515 and Yamaha 5830 and got the same response, one says the Pioneer the other says the Yamaha.Neither is properly set up in the store to try out so I left out of there with a gift certificate.I wish I never dealt with Best Buy concerning a receiver but there service was much better when I bought the first receiver a few years ago.Im even more confused now,WHAT SHOULD I DO!
