Bluesky,
The biggest issue is going to be the sound card, not the mic. An inexpensive Audio Technica ATR-30 will sound much better going into a good mic preamp, than the best mic going through the cheap sound card built into the computer.

You might consider something like this:

While it may be set up for Podcasting, you can not install the software (or you can) and still use the higher quality audio interface to get into the computer. You may want to upgrade the mic later on, but it's better to spend the money on the interface now, and have that, versus spending $100 on just the mic, only to find out it sounds like crap with the mic pre that's on your sound chip.

Now, having said all of that, I'll give you a little more background.

There are, essentially, two types of mics, Dynamic and Condensor. Dynamics are good all around useful mics, and are used in a variety of applications. As stated earlier, Shure makes some very nice ones. Dynamic mics don't need any extra power.

Condensor mics need a power supply, called Phantom Power or Phantom Voltage. It's 48vdc. If you get a Condensor mic and do not have a source to provide that voltage, the mic will not work.

All microphones put out a VERY low voltage, and along the way, need some sort of amplification. That is where the Mic Preamp comes into play. A mic pre is a device that boosts the voltage of the mic to an acceptable level that the electronics can be used.

If your computer sound card has a Mic Input, you have a mic preamp. If you have a Line input, you can not plug a mic into that and have it work. Most PCs today color code their sound jacks, the green is out, the blue is line in and the pink is mic in.

USB mics have an internal Preamp in them.

As I've stated earlier, a good quality mic pre will do more for an inexpensive mic than using a good mic through a poor mic pre. Since most 'sound cards' in computers today are nothing more than an onboard microchip, you should not expect stellar performance out of them, no matter what mic you put in there.

The microphones you listed are not anything that I would use. The Behringer would be about the closest, but I don't like USB mics.

If you can afford to double your price, you might like this, also, but will need to purchase a mic boom to go with it.

This would be another good choice:

I've given you several options based on your requirements. There are other ways around this, also. You can purchase a small mixer that has mic pres in it, the Behringers are good, and then run the output of the mixer to the Line In of your computer sound card, but you still run into a similar issue in that the quality of the sound chip isn't all that great.

For your needs, I think USB mic pre or the USB interface and the small mixer I showed you earlier, is the way to go.

Good luck to you,

Gary

I'm blessed watching God do what He does best. I've had a few rough years, and I'm still not back to where I want to be, but I'm on the way and things are looking far better now than what they were!
