What about the other options out there, such as
www.Shadetreesoftware.com and Vag-Check? Anyone use either of these?
Shadetree requires the use of a Palm OS device, and your code is basically married to that device. If you get a new Palm, the software will no longer work, which really sucks. The Vag-Check utilizes a Pocket PC platform, but you're on your own as far as getting a cable. Vag-Check is free to download for the time being. Shadetree package is nearly $300.
