Saracen Traverse - too large - replacement advice

Hi,
I have a Saracen Traverse (a few years old now.. not used much at all). It
hasnt been used much because its too big for me, I think the frame is 22"
maybe 23". On tip toes I can er rest on the crossbar.

I am after a bike for leisure use (road and walkway.. not hardcore
mountains!).

Any recommendations? Looking to spend under £200.

I plan to try and sell the Saracen Traverse, I assume the best bet would be
a local newspaper?

Thanks
