The VOLTCRAFT 610-2 is a less expensive option than the GW Instek GDM-8245, but it also has fewer features and a lower accuracy. The Peak ESR70 Atlas and Peak DCA75 are more specialized tools for testing specific components, and they are not as versatile as the GW Instek GDM-8245.

Ultimately, the best digital multimeter for you will depend on your specific needs and budget. If you are looking for a general-purpose DMM with a good balance of features and accuracy, the GW Instek GDM-8245 is a good option. If you need a more specialized DMM for testing specific components, the Peak ESR70 Atlas or Peak DCA75 may be a better choice.
