I have one of the more basic UNI-T multimeters and can highly recommend it. It's always there when I need it (the single 9V battery keeps it going for years) and has great precision.
One thing that I don't have - and really want to have - is a variable power supply with constant voltage/current. They can be used when you have an unusual battery you need to charge safely, for instance. Unfortunately, they always seem inordinately expensive considering that all they are inside is a few coils and some ICs. I've looked into building one myself, and found the very informative EEVBlog series on it[1]. However, there's one thing I don't understand: how do you compensate for the voltage drop over your current measuring resistor? Is it a simple linear equation and you just boost the voltage accordingly? I'd love an explanation!
