Price range of USB microphone for recording singing?

I want to record myself singing to put into a track that I am making on FL Studio. I am on Windows XP. Can anyone tell me the price range and/or suggest a model of a USB microphone that I could use to record in reasonably high quality in FL Studio?Someone told me this:"They can go anywhere from $50-500+ for a studio grade USB mic. I used to have one that was amazing for around $150 but i can't seem to remember the name of it. Just Google: studio usb microphoneIt should come up with something that might interest you "Another person told me this:"Digital Arts compared popular USB mics like Rode Podcaster, Samson G-Track, Blue Snowball, Marshall MXL.006 USB with a professional quality microphone"And a third person told me this:"You can get high quality voice recording from a standard voice-over microphone. Go to radio shack and buy a Microphone to 35mm (computer headphone jack) and just plug it in. You will have the high quality format with a fraction of the cost"What do you think of these answers, particularly the last one?
