I need to buy a scan tool. I narrowed it down to these three. All three are from MATCO: MPS700, 3160 or 1403. http://www.matcotools.com/Catalog/to...page=13𐍼 and http://www.matcotools.com/Catalog/to...&page=7𐈗. If you have any other suggestions on a scan tool feel free to post them up, and tell me why it is better or why you prefer it. Thanks, Art...
