I was looking through ebay and it looks like there are OBD scanners that are not that expensive. I think it might be a good idea to get one of these not just for my xb but for my other car too. The cheaper ones are only a bit over $25 with shipping for "but it now" and I guess they get more expensive the more fancier it is. What do you guys think? Does a cheap one work on our xB's? Or do I need to get the fancier ones? I think those who are especially putting on turbos and such would benefit from one of these.
