Decent UK clipart?

Hi

I'm not sure that this really fits the Edugeek remit, but as this ICT technican gets asked about anything that involves a computer in the sligthest way, then I shall pass that query on to you all.

I do the school newsletter (amongst many random non-technician related tasks), and I'm looking for some decent, education related, clipart to make it less bland.

I use a lot of Discovery Education stuff but it's all very American and not always suitable.

Any suggestions? I'm prepared to buy something (inexpensive) if it's out there.

You can download a lot more free clipart from the Microsoft site, i'd try that and google before splashing out any cash.
