Potential Kx boxed + kit lens for sale

Hello,
I am thinking about selling the Kx, I know it helps to put a price tag but I am not sure what level is right.

Mine is in very good condition, bought from new from a shop in Bath (have the receipt). The kit lens (18-55mm) has never been taken out of the box (nor its wrapping paper). I have the box and accessories etc..

I saw this one in similar condition on ebay sell for just over £200 (well mine has more than 10 clicks on it..):

Anyway let me know if you have any interest - thinking to sell just under this price tag..

the camera is in London so welcome to try/test it.
