With the single exception of looking for minor current on water pipes, I can't imagine a situation where a home inspector would need to be able to measure milliamps. And even that exception is pushing it. If you're going to use it on the job it'll be for testing the operation of heating elements in water heaters, amp draw at compressors, operation of electric furnace/heat pump elements, and for more in-depth testing of receptacles than you can do with a three-light tester. That's all pretty crude work. You don't need anything more precise than a tenth of an amp and you don't need true RMS. Any of the baseline meters from the major manufacturers will be fine. I started using a lot of UEI equipment because they were headquartered here and I could stop in for free repairs that were done while I watched. After a while, I just got to really like them. Sperry & GB are fine. It's hard to go wrong with Fluke. Like point & shoot cameras, it doesn't really make a whole lot of difference.
