UK budget microphones?

I know that gaming headsets are all the rage these days, but I've got a set of circa 1999 speakers, and I'm quite happy with them. Can anyone link me a dirt cheap mike that gets the job done reasonably, for less than £20?

I'm not talking anything remotely quality here. I'm just looking for a standalone mike that people can understand my voice from, when I'm talking on mumble or skype.

Cheers in advance, Isaac.

Just go into a PC world and buy a nice for around £12 pounds. Any will do if you don't care about quality. Maybe look for one with a Skype logo on its box or something like that.

The Zalman Clip-On should be around 10 pounds. I've seen pics of people making a mic stand out of coat hangers. :)
