Before you give up on your Canon A80, you should read about methods people have used to fix a lens jam on the Canon.
You may be able to fix it yourself.
As for CF cards on cameras.
Small cameras have been moving away from the CF card for several years now.
The only cameras that use CF cards are cameras that sell for over $500.
SD cards are the most common for small cameras now.
About 18 months ago I purchased a Canon Powershot A80, the lens jammed about a month ago and the third party warrenty provider is charging me $125 to replace the lens. At this point I'm looking to purchase a new camera, I'd like to get something that has 4.0 megapixels and also allows for a CF card since I used a CF card on the A80. In terms of price, I'd like to keep it under $300 if possible. Any suggestions???
