Clearance HF OBDII scanner

http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=98568

This is at my local Harbor Freight for like $30. Basically I need one to check my engine light (Jeep isn't running good enough to get to Autozone)

Was wondering if anyone had any feedback on this scanner. HF is no longer going to carry this item hence the reason it's on clearance. If this can at least give me the code that I can later look up online that would be great.

It's worth $30. Nothing special, but it will show codes and clear codes, and works with the newer CAN bus. If it's like the el cheapo one I've got, it give you the code and the definition.

I wonder if they have that for clearance at my local HF.
