Multimeter recommendations

[BrianG]

Define "weird readings". If they are just off, you can "re-calibrate" them the quick and dirty way by using a known good reference meter (like a Fluke), preferably using one that is either new or recently professionally calibrated. Most, if not all, meters (even cheap ones) have some trim pots inside which can be used to tweak the readings. It depends on exactly how accurate you want.

Other than that, pretty much any meter in the 50 price range will be equivalent IMO.
