Lots of mics in that price range. Dynamics wise record in 24 bit, not 16. And get a mic that handles the SPL of the task. Bear in mind that SPL specs are measured at 1 meter, not the 6" that they'll be from a lot of sources. If mythbusters is to be trusted, the human voice can break glass, so having headroom in terms of SPL tolerance can't hurt. At least 130dB IMO for voice. Without the pad switch if available. At least check this spec, some mics only handle SPL in the neighborhood of 100dB, which is okay at talking levels, but not much use for anything else.
It'd be hard to recommend a mic without knowing where you live. Shure and Audio Technica for the USA. Sennheiser, Neuman (not in that price range), and others for the other side of the pond. Rode if you live in Australia. And if you live in China, by all means get a mic made in China.
You could always tweak the EQ of your SDC accurate ones to see what tickles you. A lot of manufacturers have frequency response curves that could help guide you on those tweaks. One way to get something different from what you already have. Perhaps a frequency sweep recorded on your current mics to make them ruler flat first. And look out for frequency graphs that are pretty much drawn, not measured. Which would indicate a manufacturer NOT to trust. Or manufacturers that don't publish ANY specs for their mics.
