Desktop mic and echo

Hey guys,

I've got a Corsair Vengeance 2000 right now (USB Wireless Headset).
However it's not very comfortable anymore, nor do I like having a headset on all the time.

So I've been thinking of selling it and getting a desktop mic.
I'm just wondering how the echo is seeing how I've got a Razer Blackwidow with MX blues and like I said I won't have a headset on most of the time.

I use my mic mostly for teamspeak / skype so nothing professional. 

Are there any good desktop mics around for < €100 that would fit my needs?
