There are any number of products on the market at all levels. If you want a handheld unit, the Baum might be one of the few choices that will do both. Companies like EASE diagnostics sell cables and software to be used with a handheld or laptop computer that can do both.

To me, on OBDI cars a scanner is almost always unnecessary. Depending on the vehicle, you can draw a code with something as simple as a paperclip to short a few pins on the connector under the dash, turn on the key and observe the flashing codes of the Check Engine light. Most any OBDI car has a simple way to draw the code if you will do just a little research.
