There are several Flash Memory based camcorders that should fit your needs. Flash memory can be “skipped” to without fast forwarding and rewinding as in tape based systems. Canon has several to choose from under $500. Stop by your local BestBuy and try one out.

Generally yes. The camera should have some type of USB port and the cable should have been included with the camera. Check the owners manual about included items. If it lists a cable and you just recently purchased the camera take the cable and the receipt back to the store and explain that the cable is missing.
