Getting a good setup... mouse/ headset etc

[Superdannyb]

I have a sweet computer with a 24" monitor let's leave that alone

What i don't have is a nice mouse or headset... and i want both

So, what are some good ones for source? Idealy i'd like a wireless mouse that will give constant performance as the battery deteriates. I've read good things about the razer mamba but it's a little pricey.

Headset, i have no idea.

So, suggestions on both please?

Total max budget something like £150 but would like to spend less tbh.

Thanks
