IMO Canon has the most intuitive interface and is more consistent across the model line(s) than most other manufacturers.
The SD750 that BigDaddyTX mentioned is good. Most of the Canon A Series and PowerShot series are pretty solid. I checked BuyDig and they have the A590 IS for $144.90 shipped. BuyDig wants $169 shipped. Those would both be very solid entry level cameras.
