Ok, shopping for a tachometer, I have decided I want an autometer 5" sport comp #3905 with shift light. Problem is, these critters are in the $200-$250 range. I can get one exactly like it only it is "Autogage" instead of "Autometer". Same company produces both tachs. The autogage is only $100-$150. So the question is, what am I getting for $100 more dollars? Is it truely just the name? Shopping around on ebay for tachs, I have found many half decent looking el-cheapo tachometers. I know you get what you pay for, but I also know that you pay for a name. So does anyone have any bad experiences going the cheap route? Can you mess up a simple insturment such as a tachometer?
