If you want to take a decent photo under the water, get a decent camera with a underwater housing. £5-£10* does not buy you a good underwater camera.
* $10 - £20 USD
Hey Fergie,
Sorry to hear that. Though to be honest, I wasn't surprised.... Like you said, you just can't get a decent camera for 20 bucks. Thats why I finally broke down & bought tht Olympus, which is great for the <15' depths... Deeper than that, & you'll want the housing like you said....
