I would agree with Behringer as a cheap but pretty good brand. Depending on what you plan to plug into I might go with the C-1 or C1u, just because condenser mics are generally more forgiving for people who don't have training in voice projection.
They're both well beyond your price point of $100 or less,
but my favourite studio mics are (in order of preference):
-Shure SM 5B (unfortunately no longer manufactured but they
are great mics)
-Shure SM 7B (with the switch on the back set to make it
sound close to a SM 5B sound)
Combined with a decent mic amplifier
