6) Final Thoughts – Choosing the Right Multimeter for Your Needs

Each of these multimeters has strengths suited for different users. The Fluke 117 remains the gold standard for professionals who need high precision, while the Kewtech KT117 and Klein Tools MM325 offer good value with a focus on safety and durability. If you're looking for a budget-friendly option, the Draper DMM201 is ideal. For a versatile tool with extensive measurement functions, the ASTRO AI DM6000AR is a great choice.

When making your decision, consider factors such as electrical testing needs  and whether additional cost for accessories is justified. Also, take advantage of any free delivery and returns service when purchasing your multimeter. 
I am of the opinion that when it comes to electrical tools, always buy the best that you can afford as spending less now may mean that valuable features are not available without purchasing another, more expensive model later on. 

Happy testing, and stay safe in all your electrical work!
