[Blind-sysadmins] Accessible multimeter

Hello, A little while back maybe early last year or so there was talk about an accessible multimeter. I now have the need to get one and by the end of today the means to do so. My primary use for this device as of now, although this might expand, in the future, is as a computer power supply tester, a PSU. I lost one for sure last week and have doubts about the reliability and functionality of another, and i've got two others I have no clue on. If anyone has any recommendations i'd appreciate knowing about them. Also, I am by no means an electricity guru so if those with experience could talk things with me I'd appreciate it. Thanks. Dave.
