Not sure if this is the correct forum to put this in....

I am looking for OBDI/II Scan equipment. Can someone recommend me a good scan tool? I have 2 older cars that need the OBDI, but I also know that in the future I will probably get a car with OBDII; so I would like it to have both features.

Can someone post a link to the one they recommend? Thanks. Price range? $0-$350. Thanks.
