Genysis Touch. Ive had one for about three years, the Mac version is more expensive for the same thing, they run around 3,500 and its well worth it. it come with a bunch of OBD-1 cables EXCEPT the jeep and GM (for SOME reason!) the good news is they arent real expensive. around 50.00 each. the scanner has gone through quite a few updates, and they are downloaded automatically. 2-3 a year, some are software improvements, others are to add new vehicles/codes/information and to update Repair Trac (a kind of free version of Identifix) it is a very detailed scanner with lots of information, it is wireless when connected to the car (has a box that is plugged in and connects via Bluetooth, or you can plug it in directly to the USB port on top)
the box (VCI interface) also functions as a J2534-1&2 passthrough and with any laptop can do PCM flash/programing (you CAN use the scanner, but it is much easier to use an old laptop)
