I'm thinking about picking up a meter not going to be leaving it in the mobile have heard good and bad reviews and they seem a little overpriced only other meter I seen which was cheaper as a comparision was a workman .
I use a radio shack one in my travel bag. They are still in business with stores open in the larger towns. They are supposed to be getting their on-line store back up soon as well.
I just checked on line and didn't see any meters. I would buy a cheap one and check it initially, and then periodically, for accuracy against a high quality meter. Astatic looks like a good deal on ebay.
