If you only want something to read the codes and clear them, there are plenty of code readers on eBay in the $20-$25 range. Save yourself some $$$ unless you're going to do extensive diagnostics. I got one of those earlier, but it was not enough info for me to do diagnostics unless the problem was a sensor that gave a code.
Here's the difference between the two from my previous problem with vacuum. The regular code reader gave me a code of "Fuel Injection Circuit 1" and that's it. All of the injectors were working fine so I bought the AutoTap. With it, I could run the car and record the output of all of the O2 sensors, the fuel mixture and other settings. By watching the different sensor reactions when the car stalled I could see there was one area that was lacking O2 because the sensor after that point was wide open and it still stalled. Traced it back and found a cut in one of the vacuum hoses. Replaced the hose and it's been as good as new.
