Jay, I bought two insulation testers (Megger is a brand name) in April. A used Fluke 1520 off Ebay for $275 and a new inexpensive (cheap) insulation tester on Amazon (Electronic Specialties 550 Insulation Tester for $162). Both work fine. The Fluke has better accuracy that I need for very specialized "field wet resistance testing" (FWRT). However, the cheap tester works great for finding faults in conductors and severe faults in modules.
I bought both to determine if a cheap meter would work and the answer is YES. The key is performing the tests properly and safely which requires test procedures. The other key to actually use the tester. Several people own these devices, but never use them. They should be used on every installation after the wire is installed to determine if any wire damage is visible to the tester. Even though this will not solve all field mistakes, it will catch the marginal problems that may be too small to be detected by the GFP circuit in the inverter.
