I don't think buying gauges by name will yield better results. Some gauges have an adjustment to decrease the percentage of inaccuracy and at the end of the day they do 2 things - read resistance or read voltage. It probably depends as much on the sender unit as it does on the gauge (unless it is cheap-@ss garbage then don't expect it work well or long) You will find a lot of gauges are the same manufacturer but different brands. Summit seems to have a good rep and deals on ebay are pretty good. All comes down to what gauges you need and the look. Even if they aren't super accurate you can tell at first glance if something is up with the engine or charging system depending on what you've installed.
