Volvo Repair: 2000 S80 check engine light on., obd scanner, reader scanner

Question
Hi there. I have a 2000 S80 2.9 with check engine light on. I've been to Pepboys the other day and I saw this OBD reader/scanner/resetter. I don't know if this OBD scanner/reader is compatible with my car. I would like to know if there is an aftermarket OBD II reader/scanner/resetter available for my car. If there is one available, can you please tell me what brand and where can I get it? Thank you very much in advance...  

Answer
Hi Joey,
           Lights that stay on can be such a major pain..
      If you are really interested in aquiring equpt. to read codes...look up a Snap-ON salesman...on the net...they often have used stuff and you can save hundreds..on super good quality tools.
               Good night,
