Cheap and inaccurate solutions:http://www.apogeekits.com/multimeter_dvm850bl.htm -> Cheap solution, very low accuracy
http://www.apogeekits.com/digital_multimeter_dmm810.htm -> Cheaper than the first with accordingly accuracy
http://www.apogeekits.com/capacitance_meter_dvm6013.htm -> Not a multimeter, this is capacitance meter
Just "better than before" solutions, up to $30:http://www.mpja.com/prodinfo.asp?number=16372+TE -> Much better solution, no transistor tester though
***http://www.mpja.com/prodinfo.asp?number=16562+TE -> Same as before, but with extra auto range selection (that you pay $10 extra to get it)
"No way" solutions:http://www.apogeekits.com/multimeter_dvm345di.htm -> Expensive solution, very low accuracy, fancy (and almost useless) PC connection
Futurlec -> A nice place to get almost all of your electronic parts, very good prices and fair transport charges, except LCDs and Multimeters...
If you go for as expensive as $80 or more, then consider the links spicom gave you, or better, search for a fluke. There is indeed great difference. For example, i measured the output of my power supply (that should have +5 and +12 volts) with a cheap multimeter. About $13... And then i measured with the fluke. Here are the results:
Voltage | Cheap | Fluke |
5V | 5.4 | 5 |
12 | 12.6 | 12 |
17 (5+12) | 16.8 ( ) | 17 |
That is the meaning of accuracy. If you do not mind having those readings, then go for the cheapest. There is no reason to spend more, really.
