I was able to pick up a 327 scanner on ebay for about $22 with shipping. It works with all software I've found that supports the 327 chip. Some programs were a bit of a pain but it wasn't actually going into 327 mode.
I'm really trying to find the open source obd2 programming site. I should have bookmarked it.
**edit**
Found it!

Since I know the Durango can be reflashed via the opd2 port, I wonder if I could make it work with this program? Nice thing about OpenPort is that it can datalog to MicroSD without a laptop since it has a standalone processor on it.
