Any mutual conductance type, as emission is ... well emission. Check eBay lots of them that "Grandpa used to use this old tester thingy and plugged bulbs in to" (not my words). I would not waste time on a straight emission type, a combo is good though... As far as what ones do what, Google is your friend... I myself have a TV-7A, Not the D, but works well enough and a Sencore 140 that I have added test data myself to.
