Thanks for your reply.
The quality of the USB logitech I tried was no where near that quality. It was not better than my headset, which I felt wasn’t a big deal, as the price was similar.
After much consideration I finally chose this:
http://www.amazon.co.uk/gp/product/B003DSI62U/ref=oss_product, which is a AKG Perception 120.
I chose the USB option because I still had so many questions about the other route. Questions that take a while to get answered in forums and then lead to other questions etc. If I could have walked into a regular retail store I might have gone with a different set up.
I am very happy with the quality I receive and just need to make a few changes to my recording environment and I will be done. Although I may get a spider mount if I see one at a good price that I know will fit my mic.
