I have been looking at getting a new stereo receiver over the past month or so and I have thought about buying a refurb. In particular I have been looking at what Ecost and Ubid have. Has anyone bought a refurb receiver from Ecost or Ubid? If so, how long have you had it and have you had any problems? I would think that with a receiver that if it works that it will most likely work for a long time.
