Which amps cannot be repaired locally?

Hi all. I purchased a Niles S-1260 a few years ago and it started shutting down recently after a few minutes of play. I called Niles and they asked I ship it to Louisville for a $650 flat fee plus shipping -- they charge that for any repair. I decided to take it somewhere locally and they could not find spare parts (a controller board or controller board IC). I called Niles, the regional rep and the local rep and none could provide me a controller board or any spare parts. Had I known that, I would never have purchased Niles. Are there other companies with similar policies about not providing spare parts for local repair? Thanks
