Any suggestions or recommendations on which one to get?

Also hoping to connect this to the Iphone as well.

If you access to a PC grab a copy of "EOBD Facile" from this site:
Download - Outils OBD Facile

Look up the Hex numbers for the OBD modes for the P38a on this page:
List of OBD2 compatible vehicles - Outils OBD Facile

Start up EOBD Facile and in the File menu go to "PID Decoder"
Enter the hex number(s) from the Mode 1 column into line one (if there is more than one number for a mode enter on the following lines), select Mode 1 in the pull down menu and click decode.

The program will list all the OBD PID's available in the mode.

Repeat the process for mode 2.

I can't see how to cut and paste from the program, hence the DIY instructions.

Basically the Td5 has bugger all coverage (but I guess you know that already), the P38a has significantly more PID's being a V8 sold into the US, and the Holden isn't listed but should have a significant amount of information.
