Buying stuff off of Ebay is always a little hit or miss. You almost have to just take the plunge and hope you don’t get burned. That is exactly what I did for a couple new panel meters. I wanted a little more resolution on my home brew power supply and came across a couple 41/2 digit volt and amp meters for $5-$10 bucks each. These types of meters seem pretty prevalent across Ebay. Just do a search for “panel meter” and you will have a bunch to choose from.
So far my first impressions are really good. As you can see in the photos these little meters are spot on, even without a trim pot in series to make finer adjustments. If you have been looking to buy one of these but thought the price was to good to be true, I say go for it. I’m sure that they may not last as long as the more expensive ones, but I’m okay with that for now.
