I'm looking at this AutoXray diagnostic scanner. They are asking $230 for this thing and was wondering how good of a deal is this? Pratical or not?

For a few dollars more you could have diagnostics and tuning with HP Tuners (http://www.hptuners.com). I work directly with HP Tuners so if you have any questions don't hesitate to ask. :D

Is that the thing they plug into my car to see what codes it has?
