Here's a less expensive option from Canon that gives you 10x zoom:

Amazon.com: Canon PowerShot SX120IS 10MP Digital Camera with 10x Optical Images Stabilized Zoom and 3-inch LCD: Camera & Photo

Zoom seems to be one of your most important requirements.

There are some minuses on this one compared to the higher priced cameras. The form factor vs. the SD may be a deal killer (see the customer-submitted comparison pic on Amazon). Also, check out the customer reviews which are mixed.

Also, it uses AA batteries (can be a plus since you can buy a boatload at your local warehouse store for about $12).
