basic code scanner for 1993 taurus srs

Hey again,
can anyone recomend an affordable code scanner that will help with diagnostics on a 1993 srs, 3.8, auto? Of course, I'd prefer inexpensive, but as long as its reasonably "idiot-proof" no worries.
Model numbers, websites etc would be appreciated

Thanks,
DS

Earlier this year I bought the Equus Innova OBD II Code Reader Model# 3100 for about $89 online. It's very idiot proof. You can find a great bargain at NexTag. There are other types of ODB2 readers out there but the one I use is Equus Innova.
