I've decided to get a Digital camera to go along with my new Laptop for travel photography. My needs for the camera are to be: fast, rugged, manual control, and 4-5MP. I only have $700.00 so a decent DSLR is out of the question, I think.

As of now, I've decided on either the Sony Cybershot DSC-V1 or the Canon PowerShot G5.
One thing that concerns me would be that I do a lot of low-light photography, and on reviews of both cameras I've noticed complaints of 'purple fringing' around lights at anything below f/4.5..is this common for most digital cameras?

As of right now I'm leaning towards the PowerShot G5 w/ lens adapter & 1.75x Teleconverter. I use a Canon film SLR at the moment, and maybe sticking with what I know (Canon) wouldn't be such a bad idea?

Thanks for any help.
