Wtd. 18-55 lens.

I hope to sell my K5 a little later this year to possibly a student but I have no kit lens. Therefore I'm looking for a cheap lens to go with it as newbies don't usually have lenses and would need a basic one to get started. It doesn't have to be the latest WR model or in absolute mint condition as long as it's clean and tidy. (NOT PLASTIC MOUNT) and under £30.00 would be nice.
I sold my ist*D and my K10 and my K7 to students who had just started on a design course at university and needed a DSLR. I'll be mixing with a lot more this summer and one of them is sure to need a camera. If not then my mint K5 will go on here later in the year to fund a K3. or whatever comes next?
CHEERS Vic.
