AvE did a review on one of his YouTube vids about a Fluke meter that could be upgraded by just fiddling around with the circuit board inside the meter- but I can't seem to find it - might be worth the time to search his YT channel.
I bought a couple of Velleman DVM850BL off ebay to use around the house. Works great for weekend warrior and hobby stuff- I would never use it if my livelihood depended on it.
