I use and can recommend the Sekonic L-208 Twinmate. It's a pocketable handheld meter that can take incident or reflected light readings. I like that it has an analog readout so you can see equivalent aperture/shutter speed combinations at a glance, plus EV if you're into that. It takes a modern 3.0V CR2032 battery, so you don't need to worry about voltage adapters. The measuring range for both ambient and incident at ISO100 is EV3 - EV17, adequate for most indoor and outdoor scenes. Somewhat clunky, but it can also be shoe mounted. $129 USD brand new, but can be found for <$100 used.
