I used to have a desk microphone. I used it less than 5 times. As a result, I have no idea where I put it now. I never get ant new one after that. Since then, I am using the built in microphone in a laptop. It is easier as I no longer need to plug in another device. I just talk directly while using the laptop. Of course, this is OK for normal usage.
If you are a podcaster or a singer, a good microphone is a must. There is a brand called Audix which has quite a number of good microphone. You can shop audix microphones by just going to their website. Detail information on particular microphone will be able to help you during the selecting process. Get a good one rather than keep changing from one to another although the price is more expensive. It is worth it after all.
