What kind of Multimeter? Digital or Analog? If you're mostly working on cars, or IC's you will need a good digital unit, since proper voltage, ohm and mA readings are mostly read within a specific "low-high" range. Good digital units usually include a temperature probe, and an audible continuity test function. Fluke has the best options, but costs more. I have found that Radio Shack and Sears have a very good selection of meters at very reasonable prices.
Traditional analog meters are better suited for general purpose home electrical and appliance repair. They require less overall maintenace and will pretty much last a lifetime. However, high quality meters will usually cost more than their digital counterparts. Although at best they give approximate readings, because everyone interprets meter readings slightly differently.
I'm of the opinion that vintage Analog VOM's (from the late 60's, 70's) were at their peak as far as development is concerned. Hence I tend to purchase name brand Analog VOM's on e-bay. The Simpson (especially the model 260), Triplett, Eico, HP, and Radio Shack Micronta meters were probably some of the most sought after VOM's of their time. They can be had at very reasonable prices on e-bay.
Also, on Analog meters, avoid the cheap 1000 ohm/volt meters and look only for 20,000 ohm/volt units; they are much more sensitive and accurate in testing delicate low voltage circuits.
