Scan Tools

Trying to find an inexpensive scan tool. Something that not only reads the SES code, but a little more reading for tuning purposes, such as air/fuel pressure, etc..

I'm looking at Elmscan VPW (http://www.scantool.net/products/product_info.php?cPath=8_1&products_id=12). Fairly cheap, hooks up to my laptop with several software applications.

Wanted to know if anyone has expereince with this particular product, and what some of the guys around here use.

I use Autotap and a DHP Powertuner.
