Dealer Alternitive to CarMD

I recently saw the informercial on this product and I was pretty impressed with it but was unsure of the quality of the product and what it did.



From looking at reviews and these forums I’ve come to the decision that it would work much better for a car owner than for a mechanic or a dealer.



With that said, My bro-in-law has a Bday coming up and as he is the guy that goes to used auctions to stock up his lot, I figured something like this would be a great asset to him. Is there anything out there <$200 that is as convenient yet still as comprehensive as the web interface of CarMD?

I use this one I found for $139: http://www.canobd2.com/

At least it is better than those $60 code readers.
