Mastech for the DIY'er/hobbyist is a good affordable option. Extech also has some models in this price range that may interest you. Klien tools is popular with certain tradespeople but I am unfamiliar with their DMM's. If you go for a used one on Ebay, try a Fluke, Mastech, Extech and not some offbrand.
If you are concerned about readings, do some tests as soon as you get it. Chances are that unless you have access to a really good DMM you would not know it was a little off. Let us know what you decide!
