I ended up picking up the hardware and ProScan 2.0 from MyScanTool.com.  I'm waiting for Brian to release the PCMScan so I can order a copy of it too.  The gauges feature is definitely what I'm looking for.  Too bad I got my hardware too late to be a Beta tester.

I'll vote after I get my hardware and try out the different software packages.  I do know that Digimoto won't be there.  I won an eBay auction from them and am still waiting on the product.
