Hello, I am looking for a nice budget 5.1 reciver to hook up to my iMac. I do use my mac for watching blu ray movies and such as I have no Tv but mainly it will be for music. A co-worker of mine is selling his Yamaha HTR-5840 for $250 canadian and I was wondering if this is a good price? I'm not really in the know when it comes to stereo equipment and was hoping someone here could chime in with some insight. Thanks.
