I second the Ottotest scan tool also. I purchased mine about a year ago and have not had any problems with it and the tech support 'actually' listens to you with suggestions that you make for them. I have used it to diagnose many a car and also have flashed numerous PCM's and other modules with it also. I have several scan tools in my shop, I have the old red brick (old guy in the shop will only use that), a Solus Pro and the Ottotest setup. I use the Solus the most, as it is easy to hook up and go for the easy jobs. I use the Ottotest when I 'really' have to dig in and diagnose a car, I really like the scanning and graphing portion of it. The only thing that stinks about the laptop/PC based system is the dang computer battery seems to go dead when you are in the middle of something, or when you grab it the battery is almost dead. A good power inverter should take care of that problem though!
Now here is my opinion........ don't waste the money on the scan tools with the built in lab scopes. Go to Autonerdz and buy a dedicated Pico scope if you REALLY want a scope. the ones in the scan tools are so buffered, you can miss small glitches and such that you may REALLY need to see. Also, you won't use a scope nearly as much as you think you will, trust me..... been there done that!!! I have a decent scope and dig it out all of 1 to 2 times a year, if that....just gathers dust more than anything!!!

Hope this helps!!
