Can someone recommend a good code reader?

The check engine light came on in my '94 Explorer, so I figured I would just buy a code reader and fix it myself. I'm thinking it will work on my Mustang since they're both OBDI. What's a good entry-level code reader that is easy to use and reasonably priced? I don't want the one that just has a blinking light to tell you the code... How about this one:

same one i have and it works awesome. mine was $40 at kragen, but i needed it asap. it even has a memory from the last time you pulled codes so you dont even have to write them down

there was a scan tool on ebay a week ago that was an actual obd 1 scan tool that would give real time readouts and stuff. it sold for like 100 bucks
The Mustang version of OBDI does not do real time read data. You need a Tweccer RT for that.

oh, maybe i was mistaken. it looked like it would have
I have an Auto Xray 2000 which does ODBII and does read real time data when in OBDII mode. They have an OBDI cable & software add on for Fords. I called and asked about the real time data for Ford OBDI. The tech guy said that Ford's OBDI didn't do real time data.

If you thinks about it, all you ever get off the data connector is a very simple stream of pulses you can read with a test lamp. To read real time data, you would need a way to identify the type of data, what sensor it was coming from and what the values are. That type of intelligence just isn't built into a simple pulse the wire interface that you read with a test lamp. To make it work, you would need a more complex protocol to package the data.
