Microphone for youtube gaming channel

Hello.

Me and a friend want to create a youtube gaming channel (how original) and I would need a new mic.

My mic will be used for commentary and also for talking on skype, mumble etc. My budget would be of about 130$. I have a logitech g710+ and I'm afraid that the mic would pic that up. Would you have any suggestions?

Thanks

i would use a condenser mic and a usb interface.in my home recording studio i use a $50 mic and a $100 interface. make sure it has phantom power too. check these out:

this is a decent mic. but if you want a cheaper setup then

you wont need a interface for that mic but. quality is slightly lowered

Thanks ^^ I'm going to wait for a couple other suggestions before choosing what I go with. I forgot to mention, I live in Switzerland so there's a high probability that some of those items aren't easy to find over here.

I would reccoment the ATR2500 or the http://www.ebay.com/itm/Audio-Technica-AT2020USB-AT-2020-USB-Studio-Recording-Condenser-Microphone-Mic-/121120824317?pt=US_Pro_Audio_Microphones&hash=item1c335d1bfd. I belive that the AT2020 is a bit better.

I've got a AT2035, which uses XLR instead of USB, so I need an interface like Ang3lF1re's, I've got the Focusrite Scarlet 2i2, which I like alot. My setup will run about $300 MSRP; the AT2020 USB is a standalone mic and only costs $100-ish on ebay.

Also as for the mic picking up your keyboard, there's not much that can be done, just type quietly...

thanks, I will probably end up going with the at2020 seeing as those interfaces are pretty hard to find here.

A lot of people seem to have no problem with the Blue Yeti mic

I see a lot more people using the Yeti, but I use the Blue Snowball.

I use one of these and I think its one of the best sounding mics on a budget since its a dynamic mic it does not pick up my mechanical keyboard and it also sounds like you are talking in real life and its not going over the internet.  Its a very full sounding mic picks up lows mids and highs equaly and does not sound tinny.

It also comes with a desktop stand as seen on audio technicas website

Personally I am a gaming commentator an I use a yeti because it gives me more options than a blue snowball but a blue snowball would work all the same.
