Small bag for gripped 40D + 2 lenses?

[Twizzel]

Going away on a last minute cruise in a couple of weeks and don't want to take a huge amount of camera gear. I have a rucksack bag but it won't fit all my other hand luggage so need a small bag to fit my gripped 40D, Sigma 10-20 and kit lens in, which will then be put in my hand luggage bag.

Any suggestions? As cheap as possible as I am eternally skint at the mo
