There’s a positive review of the Canon PowerShot A570 over at Cameratown. Here’s a short extract from it :

“… A series PowerShots have improved with each generation and — thanks to the inclusion of comprehensive manual controls and technologies such as the new DIGIC III imaging processor and image stabilization — have become a viable weapon of choice not only for beginners but also the more advanced photographer with limited resources. … this is a perfect camera for anyone wanting real photographic control without paying through the nose. Its well balanced combination of image quality, functionality and handling (and not to forget value for money) means the A570 IS just about deserves our highest award.”

The Canon PowerShot A570 is in the $250 / £120 price bracket.
