ODB II - USB Interface - Any advice?

I have been looking at a couple of devices that will allow me to hook my computer into the ODB II port. This will likely evolve into a netbook/carputer mod.

Here are some of the units I've found:
ODB Link CI
ELMScan 5 USB
OBDPro USB Scantool

Has anyone used any of these units?

 

Not one of those. Been using a Scangauge for about 6months.. awesome device and tells me everything I need.

 

Two are under $90. I'm surprised. A few years ago, the computer-interfaced readers were several hundred. See if you can download and try out their software (demo).. that may be the biggest factor in deciding between them.

 

X2! Great device to own.

 

I looked at the ScanGuage.
Eventually my plan is to install a netbook that will handle ODB II, GPS, and the tailgate camera (I've got a 2009, so I have a camera, but no screen)

That's a great idea. Hopefully I can find something to test.
Thanks.

 

Just putting in my vote for ElmScan5 - been using it professionally for 2 years now (the system, they've been doing updates) - couldn't be happier.
