i would take a look at the audiotechnica atr2500usb and atr2020usb. the 2500 is about 75-80% the audio quality of the 2020 but with poorer built quality. its a good choice for a cheaper microphone though and likely better than the c03u or c01u pro. if you have the money i'd get a 2020usb / 2020usbplus though. or a 2020 (xlr) paired with a usb audio interface / mixer.
