Good deal on OBD-II --> Serial cable (?)

[llamacheez]

Hey I am interested in making an OBDuino for my 2008 Civic (uses CAN). Anyway, I was looking around eBay for related materials and found these cables (says there are more than ten, Buy-it-Now for $8.49, free shipping). It appears that the pinout is correct. One difference is that the chassis ground and signal ground are together...but that shouldn't matter should it? Would this be a good cable to buy? Thanks!

Also would the Seeeduino be a good choice of arduino clone? I was looking at the Freeduino SB kit, but the Seeeduino comes already assembled for the same price.

Seeeduino fully Assembled - Arduino compatible

Thanks!

I'd also like to know...the cable looks like a good deal because just the connector is $5 +$3 shipping...or you get the whole cable for $8.95 shipped. Or a I missing something too?
