The Peak Atlas testers are very good for the money-- I have used them without major issue. They offer a package I believe of 2 or 3 testers that range from testing ESR/Cap value to solid state components and a LCR tester. My only gripe about them is they are small, the leads are short, so they flop around when trying to connect to components.... often the tester itself ends up inside the unit under test, the leads are that short. I don't own any Atlas testers for that reason but I can't say anything bad about them overall. Be very cautious on those Chinese produced knock-offs on eBay-- lots of sub-quality stuff with little to no protection and reliability issues. Uni-T is one Chinese company that's producing nice testers. I own one and it's the size of a handheld DVM, solidly built, good performing, reliable, and can interface to a PC for batch testing and documenting the results.
