need help with mics

I'm looking at gettin the Tascam US-122 Audio/MIDI interface (handles phantom powered mics) to hook up my keyboard and mics, but I'm not sure what mics to get. If anyone got any advice on this, please let me know what mics work well plus the websites and/or prices if you know. Also, if u know of a better system then the tascam let me know. thanks for the time.
