Need Microphone for voice recording in good quality

Hi.

I need a microphone which I can connect to my computer and record my voice. I am not aware of much of the differences between various brands, but I do know that there are some very expensive and famous models out there which I cant afford.

I just need a mic for recording purpose where the recorded voice must be understandable easily. I would not be shouting or singing for that matter as its like just usual conversation.

I kind of looked for certain models, but I am not sure if they can be connected to PC, so here are the links:

the first one price = Rs 450

And the second one price= Rs 549

Third one = Rs 179

I am not sure about IBall quality. I would greatly appreciate any help or suggestions.

Thanks
