Wanted: Small cyclocross bike/frame, 52-53ish tt

Hi guys,
having a bit of a shuffle with my bikes at the moment - one is listed on ebay finishing shortly so it won't be too long before I have space for the next project. I'm after a cx bike primarily for cross country riding, a bit of commuting, and hopefully some racing if I get on with it. Size wise I'm 5'8 and tend to ride road bikes around a 53.5 effective top tube, so something 52.5-53.5 should be about on the money. Standover needs to be kept in mind too as I have a 31" inside leg. I'm not too fussed about disc vs canti at the moment. Ideally the frame will have at least one bottle cage mount though.

Decent alu frame and carbon fork, ideally ridley or kinesis though I'm open to offers. If a full bike - 105 5700, rival or force would be perfect, as would 46/36 rings on a 170mm chainset. Budget wise I can go up to £1000 depending on the spec, though primarily looking around the £700-800 mark.

No dents, dings or cracks. A few cosmetic marks from use. A little paint missing on the stay from chain. - Overall very presentable. Fork retails alone for £399 and £99 for the headset alone... albeit used this is very good value for money.

Saw this and thought it looked great, definitely caught my attention. Bit worried about it being a touch too large though? Does it match up with the 49 on the kona geometry chart? Obviously the frame has changed, but is the geo chart about right?

Ooh, my size! And I have a Kona Road bike in orange already. Hmm
Just out of interest, how did you come to own Helen Wyman's frame?
