Clyclcorss bike - 2nd set of road wheels

GEPC

I ride a cyclocross bike. Its made by On One and has a titanium frame so weight wise it stands up well to a lot of road bikes. Most of the time I am perfectly happy with the set up, however there are moments (like today) when I went out with a friend on a road bike and i would have liked to have been able to put a set or road wheels on it.

I am thinking that having a complete 2nd set of wheels that I can easily change over is the way to go. Can anyone recommend a set for (ideally) no more than about £250?
The other thing to bare in mind is that I weigh about 16.5 stone so I need to find the right balance of lightness and strength.

Thanks in advance for any advice.

If you get the same wheels/rims then you don't need to re-adjust the brakes
