These are 2 thread from EEVBlog that compare multimeters:
Multimeter spreadsheet (38 brands and 210 meters listed)
Multimeters that do not appear to meet their safety specs. (updated frequently)
One hint: although the xx830 line of DMMs are ok (all DMMs that have "830" on their model number are the same internally, and from the same few OEMs. They are just rebranded, and are very cheap), they are not as precise as other multimeters and not as fully featured. They lack capacitance and inductance metering, for example.
One inexpensive (but not cheap) brand is Mastech, from China. They make good, robust and fairly precise DMMs. I have a few DMMs (including 2 Flukes, among other brands) and the only one that is reading the same of closest to the Flukes is the Mastech MS8260 (around US$ 40). I use the Flukes as a reference because they are fairly new and have been factory calibrated, so the fact that the MS8260 gives the same or very close reading is a good pointer.
Another hint: it pays to have more than one DMM: have a good one that can read milliamps and another, simpler one, that can read millivolts. I say this because you'll often need to read both voltage and current at the same time, and it's a PITA to do so with only one DMM.
