1) The meter in both my Hexar RFs (and Konica S3, and Ricoh GR1, and even my old OM-2n)
2) An old-but-loverly Sekonic L-428, which doesn't get out all that much, but when it does it's usually set up for incident reading (the one thing my camera's built-in meters can't offer), although I do have the 5° spot attachment, among others, for stage shooting and the like. Not tiny, but not crazy-huge, and cheap ($50 via the 'Bay, replacing an identical unit that was destroyed in a freak accident). Uses a quartet of non-exotic S76 silver-oxide cells, which seem to last a few years between necessary changings. I've never really cottoned to handheld meters much, but I do like this one.
(Edit: I just remembered: Of all the 35mm cameras I've owned, since my first – a Yashica 5000E Lynx, around 1972 – not one of them was without a built-in meter, TTL or otherwise. Talk about being spoiled!) 😉
